"MOST of the people killed in gun violence are those who chose a life of crime."
It would be interesting to know where the numbers for "most" came from? Certainly not the people killed at Pulse or the two teens killed at ClubBlu last week. Not the police officers murdered this past year, and not the man shot in the back by his neighbor in Fairbanks (he was seriously injured but apparently has survived) or the young man killed while pumping gas in Anchorage. How about the Sandy Hook kids, the people murdered in the Charleston AME Church, San Bernadino, Colorado Springs ... none of which involved someone being attacked in their home? The children killed because adults were careless were criminals?
SOME people killed in violence have chosen a life of crime but a growing number have not. What do we do to protect them? Arming more careless or unstable fearful people probably will not help. 
Time to change the way people think about when and where to use a gun.
