We know who they are - they're registered!
Why is it that those who steal guns, who then go and kill movie goers and children in school have never been a conservative NRA member?
Ft Hood - Registered Democrat – Muslim
Columbine - Too young to vote; both families were registered Democrats and progressive liberals
Virginia Tech - Wrote hate mail to President Bush and to his staff - Registered Democrat
Colorado Theater - Registered Democrat; staff worker on the Obama campaign; Occupy Wall Street participant; progressive liberal
Connecticut School Shooter - Registered Democrat; hated Christians
Common thread is that all of these shooters were progressive liberal Democrats
INTERESTING..., isn't it?
