The Beltway Snipers have been of more than casual interest to me for numerous reasons. Even before we knew who they were or their motives it was source of concern because of the damage it did to our right to keep and bear arms. I was also asked by a program manager when I worked at Pacific Northwest National Laboratory if I had any ideas on how to catch them. The labs were getting asked by law enforcement for help. I didn't really have anything other than what was already known. I don't really think short of creating a surveillance society of both video and audio sensors that new technology can offer much help in catching criminals of this nature. But that's getting off my main impetus for this post.
Michelle Malkin points out one of the criminals has confessed to another murder in Arizona.
It's amazing to me how much these criminal got away with before being caught. And then they only got caught after they started leaving notes for the police!
It appears that because their motives are not obvious from the crimes it was extremely difficult to find suspects to examine for evidence. Scary stuff.
