Six months back, one of my nephews was attacked by 6-8 blks back East while he was walking to his vehicle. They beat his head off the street, several skull fractures, lucky to be alive but still suffering vision & hearing loss. My nephew was a big boy, 6,2 played football, big body builder; also an accountant; but he didn't have a 1911 on his person that evening.
Many years back, I was shot at by a car load of blks in a failed robbery attempt. I'll never forget those orange flashes and the bullets whizzing by. I didn't have a gun on me that night either. I've relived that incident in my mind many times. I've been armed ever since and for the life of me it has never happened again all these years. NO matter that I'm ready to go with Treyvon nowadays.
Sad State for our Country.
As for your “connection”, it’s pretty easy to see the correlation between demographic percentages and violent crime rate in any area of the country, so much so that you can pretty much say that one indicates the other.
