No party is responsible, there is a rise in crazies an nothing more. Back in Teddy Roosevelt's day the party bantering was every bit as bad as today. The issue is the nut balls we have . I am so sick of the innocent people that continue to be victims of such insanity. Maybe it is time for all good people to figure out how to defend themselves, get some training and get an eye for security threats where ever they go. It is a sad world we live in. Get a concealed carry permit.
