The Interrupters, current playing at the Siskel Film Center.
Awesome documentary about CeaseFire in Chicago. I primarily covers 3 of the violence interrupters, but gives some notice to many of the others that are part of the CeaseFire project. Almost everyone that is part of CeaseFire are former gang members, murderers, etc. Basically formerly crappy people who have realized they had very wrong pasts and are trying to use their cred, even legendary street status, to prevent violence and change the culture they grew up in. The lengths they go is just beyond incredible and just makes me gobsmacked.
This is a totally see it, do not pass go, documentary, IMO.
