Ok - so you find the footage from night of the murder - I'll have that full write up shortly.
With regards to removing you from a video feed, that really is complicated work - so I imagine it is much easier just to delete the file in its entirety.
As far as Matrix action - here is a transcript of a Matrix action I did via email with one of my PnP players. This was the first time I did it, so don't pay too much attention to the die rolls, since some of them are wrong, but this hopefully will give you a better idea of Matrix action.
After several hours of hunting down the mysterious symbols, your toga-clad persona manages to turn up the Host in question. Located on the Public Grid, the area around the Host has seen better days. Icons for various devices float by, blinking in and out due to poor connectivity. The few other personas in the area move by quickly - focused on their tasks, seemingly unable or unwilling to make eye-contact. Although you dislike moving on the Public Grid, the signal distortion from it to your nice clean Corporate Global Grid causes everything to be blurry, and there is a constant static hum in your ears like really bad fluorescent lighting. Taking a moment, hop from the clean corporate world to the slums that Wafselwyc inhabits when he comes to the Matrix.
Alex takes Grid Hop Action. Normally this would require a Hack on the Fly (Hacking+Logic [Sleaze] vs 4 or 6 dice) - but since everyone has access to the Public Grid, you can simply move over.
Now that your are on the Public Grid, the blur and the noise get better, but only a little. You quickly do a circle around the building, and see there is only one entrance. You step up to it, take out a hammer and chisel, and prepare to make your mark on the Host.
Alex now takes a Hack on the Fly action (Hacking+Logic [Sleaze] vis Int +Firewall). The Host's rating is 6 (which is the number used for all of its Stats), and its Attack is 9, Firewall 8, Data Processing 7, Sleaze 6). Alex Rolls a base of 11 dice, +2 for being in Hot Sim, -2 for being on the Public Grid. Due to distance from your home to the Host, there is a Noise penalty of 3, and it is located in the Sprawl Downtown Spam and Static Zone for a further Noise penalty of 2- making for a total penalty of 5 dice. Alex, however, is running Signal Scrub, which gives him a Noise Reduction of 2, and then his datajack running wirelessly gives him a further noise reduction of 1 - reducing the noise penalty to 2. Thus Alex will roll 11 -2 or 9 dice, while the Host will roll 14.
Alex decided to use his edge:
Alex rolls and gets 8 hits
http://invisiblecastle.com/roller/view/4166661/ and then rerolls his 6s and gets 3 more
http://invisiblecastle.com/roller/view/4166663/Since you used Edge, you get to count all 11 hits.
The Host rolls and gets 7 hits
http://invisiblecastle.com/roller/view/4166666/Alex proceeds to engrave his mark over the door of the host, bringing a very tiny amount of Renaissance style decor to the otherwise drab building. The lock to the door springs open, and he steps inside. The interior of the building is even more drab than the exterior - if that is actually possible. Alex notices there are several people wandering about the building. Most of them are large burly types, covered in prison-style tattoos. Alex puts away his tools, and with a wave of his hand, changes his toga to something a little less conspicuous - to fit in with this lot, it seems that a black wife-beater t-shirt and black cargo pants fits the bill. With a brief flourish, the pockets of the cargo pants are adorned with your mark, to give a semblance of style. Alex begins to look around...
Alex begins to walk through the building, attempting to look as if he belonged. The other personas in the room seem to be doing the same - not interacting with one another, but rather going about their business. There is a large man with a snarling dog on a leash patrolling the inside of the building - as they pass Alex, the dog sniffs at him and growls a little, but moves on. The interior of the building looks like a converted warehouse - with the storage on the ground floor, and the offices on the second. On the ground floor Alex makes a note of several devices of unknown purpose on the main floor, they look like electronics, but without further examination it is impossible to tell what they correspond to in the real world. Occasionally one of the personas walks over to them, interacts with it briefly, and then either moves on or shimmers briefly, their human looking form being replaced by an icon that looks like the star symbol on the door.
Ok - the guard and dog are Patrol IC - as you are not doing anything and you have a mark on the Host, they cannot tell you don't belong. Devices and Personas show up in the Matrix - When you are logged in, your persona is there, when you log out, the device that you use to access the matrix is there - so the shimmering from persona to icon is obviously someone using a commlink or deck to access a device through the Matrix, and then when he/she is done, logging off, and so their device still shows. If you were to disable your deck/commlink's wireless capability, then your device would not show up either. You could also, by the way, "run silent' which means you do not show up except with a Matrix Perception test - but if you were to do so in the Host and were spotted, it would be a dead giveaway that you weren't meant to be there.
What's next?
Alex continues his stroll through the warehouse, nodding to various individuals in an attempt to maintain his cover. As he approaches the devices on the warehouse floor, he takes a quick glance over his shoulder - while GOD is watching, he is not in danger of drawing his wrath as of yet. He quickly scans the room, looking for any of the Orthodox Crosses that were on the outside of the building, but they seem to be absent from the interior.
Alex reaches the bank of devices and attempts to see what it is. He begins manipulating one of the devices, but is unable to figure out exactly what it does. The dog begins to sniff the air, swinging his head around, but is unable to pinpoint the location of what is bothering it. Alex bends down over his console and tries to look like he knows what he is doing.
Alex checks to see what his overwatch score is. He rolls Electronic Warfare + Logic [Sleaze] v. 6 dice getting 5 hits
http://invisiblecastle.com/roller/view/4168302/ While the GOD only gets 3
http://invisiblecastle.com/roller/view/4168303/Alex's overwatch score is currently 10.
He then makes a Matrix Perception test Computer + Intuition [Data Processing] vs Device Rating x2 (since he is now considered directly connected to the device) (now taking the noise modifier into account - rolling 8 dice) getting only 1 success
http://invisiblecastle.com/roller/view/4168309/ While the Host gets 2 out of 8 dice.
http://invisiblecastle.com/roller/view/4221826/Since it is neither a Sleaze nor Attack action, the Host is not immediately alerted.
Alex again sets to work trying to determine what the device in front of him is. His virtual fingers fly across the controls, but try as he might, he cannot seem to determine what the device is. The dog begins to bark again, and now the guard holding its leash begins to move, letting the dog sniff the ground as it tries to pick up the scent. Alex knows that while the Patrol IC hasn't spotted him yet, they know something is up, they just cannot tell what...
The Patrol IC uses makes a Matrix Perception test Computer + Intuition [Data Processing] (v. Logic + Sleaze) and gets 2 hits.
http://invisiblecastle.com/roller/view/4169277/ Alex rolls his dice (again -2 for the noise) and gets 3

Pretending to switch off the machine, Alex turns and moves away from the electronics banks and begins to walk upstairs. There is less traffic up here, just the occasional persona walking by. There are three doors in front of you, each one marked in Cyrillic letters. The first is "учет", the second "финансовый", and the third "безопасность". Feeding the Cyrillic into a quick translate program, Alex reads the following:
"учет" = records
"финансовый"= financial
"безопасность"= security
Alex moves to the Records door. The door opens at his touch, the mark he has on the host listing him as a registered user, and he enters the room.
There are several filing cabinets in the room, none of which are labelled. He moves to one at random, and examines it. It also opens at his touch, and he sees many different files inside.
Alex carefully examines the file folder for boobytraps, going over it thoroughly yet carefully. At the end of his examination, he is convinced that there are no Data Bombs on this cabinet.
He picks up the file, and begins to read it, but quickly sees that it is not in Cyrillic, but rather a gibberish that could only mean encryption. Alex pauses to take stock and determine his next move.
You do a Matrix Perception test Computer + Intuition [Data Processing] (v. Logic + Sleaze) (now taking the noise modifier into account - rolling 8 dice) and gets 5 hits (1 of which is disregarded due to your limit on Data Processing). The Host gets 3 successes (raising your Overwatch score to 15)
You are sure there is no data bomb, but at this point you can't do anything with the file unless you crack the encryption.
Alex pulls out a clay tablet and stylus, and goes to work cracking the code hiding the data from him. With a few deft flourishes of the stylus, he is able to determine the symbology behind the coding, and, with the key discovered, his deck quickly causes the previously unreadable characters to dissolve, leaving behind page after page of Cyrillic letters. As this happens, a klaxon sounds inside the building, and he can hear shouting from below as the Host has become aware of his presence, and the search for him begins...
Alex performs a Crack File Action - Hacking+Logic vs Protectionx2 (in this case the protection was 4) Alex rolls 9d6 getting 4 hits The Host rolls 8d6 getting 3 hits - increasing you Overwatch Score to 18.
It is now effectively combat within the Host, and your initiative is now Data Processing+Intuition +4d6. For the first round of combat, your initiative is 26. The initiative of the Host Patrol IC is 22. OOC, you know that the Host will now also begin to launch other IC (ones designed to hurt you should the Patrol IC spot you), at the rate of one per turn - how many total IC that can be running at a given time varies - no more than the Host rating - although they may not have that many loaded. In any event, company is coming.
Remember, in order to take that file with you, you will need to succeed in an Edit File action to copy it. You also need to determine if you want to switch to running silent - which will give you a -2 modifier, but will force the Host to acquire you through a Matrix Perception check, as opposed to automatically spotting you.
Alex dampens his Matrix presence in anticipation of the Hosts IC detecting him. He reconfigures his deck to make him less visible to the guards he knows are coming. As he prepares to copy the file, he hears the dog howl in triumph as it picks up his scent. Loud footsteps ring out from the corridor as IC begins to close in.
Initiative Pass 1
Alex 26 - runs silent, switches deck stats Host 22 - performs Matrix Perception Test Host Matrix Perception Test - 12d6 - 4 hits
http://invisiblecastle.com/roller/view/4173213/ Alex resists - 11d6 - 3hits Host - launches IC
Ok - I know you are going to use edge to copy the file - the Blaster IC is going to attack you on the next initiative pass - do you want to use edge to attempt to dodge the attack, or no? You are not sure what kind of IC the system is launching, so there is no way to know what types of ill effects you would suffer from a hit in addition to damage (you can look on page 248 in the book if you want for different types of IC).
Alex takes out his stylus and begins frantically copying the data from the folders. As he finishes copying the first file, the door bursts open and a large blonde man with a brushcut and imposing shotgun bursts in the room, and begins firing. Alex causes a large shield with the symbol "Λ" on it to materialize in front of him, and the bullets bounce off harmlessly.
Initiative Pass 2 Alex 16 - performs Edit File action - up to 14d6 with using Edge and gets 5 hits
http://invisiblecastle.com/roller/view/4173232/Host Resists and gets 3 hits - Overwatch score is now 21
http://invisiblecastle.com/roller/view/4221830/Host 12 - Blaster IC attacks - 12d6 and gets 3 hits
http://invisiblecastle.com/roller/view/4173242/Alex dodges with Logic + Firewall + Edge - 15d6 and gets 7 hits
http://invisiblecastle.com/roller/view/4173321/What do you do at 6?
You have one of the files copied, yes. You would want to use 1 simple action to Switch Interface from VR to AR, and then a 2nd simple action to Jack Out - both are automatically successful since you are not link-locked (which you would have been, had the IC hit you).
With an insolent wave of his hand, Alex slowly fades out, leaving the IC alone in the room with the plundered filing cabinets. He opens his eyes at home, cracks his knuckles, and begins feeding the file into his translate software.
I will get back to you later this week with the contents of the file.
