movie help
 

i dont really remeber much about this film, all i remeber is that it is a sci-fi film, and in the film there is a guy going around killing people with a major fucking hand cannon he calls the "judge". i remeber that the gun is semi auto( not a revolver for those who dont know what semi auto is). the only other thing i remeber is the the guy is white.

help me.

not Judge Dredd ?

most definetly not it was more of a serial killer.
