A scope. There is no way that anyone caught up in the drug trade or gang hits/home invasions is going to grab a rifle with a scope to defend his wife and child.
What I'm saying is that folks mixed-up with gangs, drugs, etc., have weapons of choice at the ready in case of home invasions and an AR-15 WITH A SCOPE IS NOT ONE OF THEM!!
No one in the drug trade is going to be working the night shift in a copper mine either.
