You Wanna Get Mad? Read This!

I'm in USA for 5 years already, and I love this country, and I'm happy to have a chance to live and work here,because most things are based on common sense (which I didn't have back in Eastern Europa), but I can't understand, why someone like this guy, even when caught red handed , why are authorities gone spend years keeping him alive, examine him by doctors who make 250$ and hour, spending thousands of dollars,on somebody who is damaged and can't be fixed. Bullet is just under a dollar, or ropes are cheaper and they are also reusable.
