What's Wrong With People?

"The Lincoln Memorial in the U.S. capital, Washington, D.C., was closed on Monday after suspicious items were found.

A bottle with liquid substance inside was found in a women's rest room at the memorial, along with a note that said "Do you know what anthrax is?" and "Do you know what a bomb is?" -Source

Seriously, what is wrong with people? I mean real terrorists would have just blown it up, so we know this was the work of some idiot within our own fold. Scary, to know we walk the streets with people like this.
