In reply to paul.

that is the big problem. Turning criminals loose instead of locking them up. 3 strikes and you are dead Bring back the death penalty for violent crimes.
Also, try anyone with a violent crime as an adult. Stop going easy on "minors" that commit violent crimes.

Classing gangs and gang members as terrorists would also be a good start.

EVERYONE of the thugs that commit these crimes has been in trouble many times before.
