We need alternatives to incarceration. Like execution.
I am still an advocate for penal colonies.
If someone is incapable or unwilling to observe our societal norms, then they need to be excluded from our society.
The penal system cannot be viewed as a binary choice of rehabilitation of a perpetrator or punishment of him. His simple removal from society is also a desired goal.
BTW, we own a vast amount of suitable locations throughout the Aelutian Island chain.
Lots of room for migrants up that way, too.
Public execution, preferably.
