A long time Real Estate closing attorney recently told me he has never seen so many people use gun permits and carry permits as their 2nd form of ID at closings than he has the last year+
IMO one big reason many people are skeptical about gun control (in the US) are that it will keep guns out of the hands of law abiding citizens but will not slow down the amount of guns in the hands of criminals- most guns used in acts of crime and violence are not legally registered And many of those guns are bought via pawn shops, craigs list etc Additionally gun control almost certainly will not stop military contractors and our government from selling/giving guns by the millions throughout the world - many of which make their way back to the US via legal and black market trade-
Needless to say these shootings are tragic- and will make hiring and attracting quality people to become police officers much more difficult -
