Dozer, I would think that those numbers would be higher as there are more than 1.4 million Outlaw Gang Members and more than 33,000 Outlaw Gangs running around here in the US. Gangs are a problem in most every major population centers. We should address the mental illness and criminals running free. Mental illness is a major problem with the attacks we have seen but most folks want to sweep it under the rug to hide it. In my opinion, all murderers that use weapons should be executed within one year of conviction. Other criminal acts with weapons involved, add 10 years to the sentence, no chance of parole. If the sentence has true teeth there is less likely of transgressions.
In my opinion, guns in the hands of RESPONSIBLE citizens is a crime deterrent.
