See, that's the problem with debating you libs. When you're adversary comes out with conclusive facts, you try to turn them around by bringing up something else. I said that gun and violent crimes in the US has been on the decline since the mid 90's, and you come back with some statistic about mass shootings? WTF is that about? What does mass shootings have to do with our overall gun and violent crime rate? Did you really think I was going to just let that slide by without a response?
Of course not. In a discussion or debate both sides present arguments. It is my opinion that you cherry picked a study to prove your point. I did the same.
Overall gun and violent crime may in fact have declined, but the cause for this may have nothing to do with guns and their proliferation in our society.
I was employed in LE from 1971 until 2005, during that period of time I observed how the criminal justice system reacted to crime in general. The 90's were rife with a new iteration of cocaine, crack. The free black market was open to all comers, nationwide, to distribute one of the most dangerous drugs in terms of addiction and low production cost. Thus we saw the rise of urban gangs and the bloody battle for turf.
Crack was soon seen by drug users as a lethal substance. Withdrawal left even the weekend user depressed and seeking more and more rocks just to alleviate their pain. Word got out and the epidemic waned.
The war on drugs had little impact on it loss of favor, it's impact on the users was enough to reduce demand, and that is likely one reason for the reduction of violence during the period post 2000.
Of course gun violence in terms of mass killings of innocent citizens has become more frequent; today more people carry more guns, illegally. Why if your premise is true, are so many so concerned that feel the need to be armed at all times?
