Because a lot more people own guns now, and Zimmerman got off.
Bingo.
Yep, the back pressure is building and the thugs are starting to feel it. What we need now are more stories about how home owners and the average citizen are defending themselves with guns. How it is a DANGEROUS profession to be a thug. The word is getting out.
The only true power that a criminal has is the fear in the victim of bodily harm or death. When that is reversed, when the victim is able to defend themselves and put the thug into the position of fearing for their life ... the criminal will change their profession or be eliminated.
BINGO!
the thugs now realize that if they, individually or in a mob go on a tirade, burning, looting, pillaging and thtreatening or beating up people with their sticks, bats, tire irons or whateve, that people will be well within the law to shoot their marauding a**..............
