In the US if you're with a group of people and there is some leader or group planning unlawful property destruction or violence, there is a very very good chance it is a fed or confidential informant operation and you are the mark/patsy to which all the blame will be assigned when you're staring at a sheet of paper that says US v [your name].

[eudamoniac]

Not really a "very very good chance", but the few instances of this happening have accomplished the intended effect of making everyone terrified of the possibility and thus never doing it.

Are you trying to say the US are snitches? Or in any case, more snitches than the Europeans? More snitches than the ex-communists from the Eastern Europe?

Not snitches but paid government workers trying to get you to commit crimes and then you get arrested.
