What the hell is wrong with people?

How wrong is this? Security is going to be way tighter after that. I can't believe you can go in with a .22 and start shooting at a museum. Apparently the 88-year-old guy has "a violent and virulently anti-Semitic past". And shooting up the Holocaust Museum in D.C. is how you get people to listen to you. Most likely people are going to be against anti-Sematics even more now than they were before.
