My son lived for several years in one of those "developing" countries dear to the hearts of liberals, for its constitution enshrined all the imaginary rights they (and so many of their libertarian allies) hold dear. But the real law was in the hands of anonymous mobs. When criminal activity took place in the villages, a band of men would go out at night, nab the suspected perpetrator and kill him. On paper, of course, capital punishment had been abolished even for the most heinous murders.
If the leftists keep getting their way, we will see the return of mob rule here too, I suspect, and it won't be pretty, because some of the suspected perpetrators will surely be innocent.
In the final analysis, it is society, not the government, that must decide issues like this.
Momma used to say "You can't legislate morality but that doesn't stop them from trying."
As long as there is a market for Max Hardcore's type of product there will be a Max Hardcore to provide it.
