So, someone dressed up as Agent 47 and started doing actions from the Hitman games in real life, apparently in Germany.

I like how a lot of the passerbys basically ignore what is going on. A lot of what I would call very urban diffusion of responsibility type reactions. (See also: https://en.wikipedia.org/wiki/Murder_of_Kitty_Genovese )

I also think that if something like that were attempted in the US it would be very dangerous since the police or a CCWer might open fire on the guy in a suit who appears to be murdering someone in public.

For me the main take home message of this is how stealth video games are really unrealistic. I don't think it's possible to slink around totally unseen in most real situations. There are always going to be lots of witnesses.
