Not so surprising really, in a nation that's perfectly happy to allow its citizens to have the right, and means, to unilaterally choose to inflict the death penalty without trial on another citizen who breaks into their home to steal the TV, or who 'looked funny, like he might attack me ', or who is a black youth walking through a 'white neighbourhood', or any number of other feeble excuses.

You live in a very violent society, that permits it's citizens the means to inflict extreme and lethal violence. It's hardly a surprise, therefore, that your authorities treat offenders with extreme and lethal violence.
