At least with gun ownership criminals can be executed Judge Dredd style. Or at least the result is the same when they are killed.
Their lives are worthless, there's no point for types who rob houses and hijack people or cars to exist.
The more that are eliminated, wiped out from existence, the better.
Ideally, they should be killed until there are none left to kill.
And empty the prisons too of serious offenders, wipe them out, their lives contribute nothing to society or civilisation.
