In France they spend six months training policemen, then they give them a gun and put them on the streets, and I don't know that that's enough. The film's not against the police - although I think that if someone wants to be a cop there's got to be a problem.
I think the importance of doing activist work is precisely because it allows you to give back and to consider yourself not as a single individual who may have achieved whatever but to be a part of an ongoing historical movement.
