The perpetrator wanted to start his own currency. among other things. It's like a line from All in the Family:

Mike: "Did you know that (x - number) of people were killed with handguns last year"

Archie: "Would it make you feel any better if there were stabbed?"

Why do we allow handguns? We just had an example of why. Because, here in New Hampshire, a few days ago, someone held off an intruder until the police showed up. The homeowner had a legal firearm and the perpetrator turned out to be someone involved with the most notoroius murder in New Hampshire in 20 years. Now said perp is behind bars.
