Pay attention to what you see in Manchester England tonight. Pay attention to what is happening in Europe. This is what happens when you disarm your citizens. When you open your borders without the proper vetting. When you allow political correctness to dictate how you respond to an enemy that wants to kill you. When you allow these radicals to travel to Afghanistan and Iran and simply let them back in.
