Then somebody should be punished so severely that incidence would go down dramatically. I dont mean 2 weeks administrative leave (or medal and promotion), I mean lives ruined, names tarnished, and/or people executed/jailed for 20 lives for mass (in)voluntary manslaughter.

In reality, in same vein quite a few US laws are set. If you are not US passport holder you are subhuman. Less rights, less care, more disposable, just a garbage to step on. We saw it enough in past 80 years to see a clear pattern everywhere US went and (mostly) failed.

For those slow in back rows - this is how you get almost endless stream of new fanatical recruits to merry groups like isis or al-queda. Dumb, supremely dumb. Yeah, 'a mistake, it can happen'. Fuck that american self-entitled rotten racist mentality. Then you wonder why whole world hates you now and what you stand for and represent. What a success story for america in past year.
