What a strange concept...
Actually arresting gang bangers to take them off the street...!!!
I wonder how many murders these bamgers committed before being picked up?
There is a an easy solution to this problem, since the gang's own the street, just have a little pow wow letting all the gang leaders know if the killing doesn't stop, each and every one of them will be put in a deep dark prison hole for a long, long, long time, until order is returned to the streets...
Then your lieutenants will be next...
Suspend Habeas Corpus for all gang members...
Arrest them en masse until they get the point...
Just treat them like the terrorists they really are.
