I agree with the people who say that punknaughts might develop in Z-zones, but only there. I think LoneStar only really monitors maybe a half mile buffer zone into the really bad areas. The rest can burn for all they care.
My tint on the world of Shadowrun is much like this. Groups like Lone Star just don't have the cash for nice toys and are mired in paperwork. Only areas that can afford folks like KE have any real security. In my worlds, there just isn't enough tax money to pay for worthwhile public law enforcement to even cover C zones well. And as long as the Punknaught stays in a Z zone, doesn't hit a corp building or interfere with organized crime, nobody (who can do anything about it) cares.
One difference is that its not aerial drones doing the monitoring. Its the people in the buffer zones themselves. Free eyes and ears. Drones are targets for pranksters and require operational costs (maint, fuel, operators). And the Star ain't exactly rolling in cash.
The more interesting question is:What is the response when it wanders out? If its just taking the freeway from Z1 to Z2, does Lone Star chase it in to Z2? That all depends on the needs of the plot I guess.
As cool as a 500lb cease and desist order is, I don't see Lone Star dropping it. That's MetroPlex guard level.
Five stars if I have my lingo correct.
