I don't know if somebody had suggested this already.
Since we already have cops - Sentinel. Why don't we have a clan for their prisoners - Cryme? (convicted thieves, serial killers, corrupt politicians, etc) They could escape their cells, during the night, through a secret hole in their dining hall (possibly created by the Vortex to help them mess with the present Clint City.) Vengeance is their sole purpose of escaping. However they must return to their respective cells before the sun rises or else they may risk themselves from a harsh detention by the sents or worse thrown into maximum security. (in this case they became CR.)
If this happens, I bet cards from this clan will have interesting stories and bios. (see Hugo's bio)
