That's seriously absurd. Are the any instances of this being enforced in a public park? I've read of many cases of getting added to the registry from public urination, but they're all in cities[1].
[1]: And usually it's not even in "public". It'd be behind a dumpster or the end of an alley. Yes it's not something we as a society want, but who in their right mind puts that person in the same category as a pedophile.
We should recognize that we cannot always judge that correctly. So you either let people out who might still be a danger, or you keep people locked up who might not be a danger. (And, in fact, you do both - all you can do is adjust the proportions.)
But people scream really loudly if you keep people locked up who arguably are no longer a danger...
Lumping all of these into one pot is another foolish idea with the list.
1) heck, we don't get guilty / not guilty right which is why I'm against the death penalty
2) in some form
This is not how justice works. If you want to create some other form of government, that's fine, just don't call prison justice.
Repeat sex offenders are effectively jailed for life.
Well, no.
After multiple DUIs, someone can have their license taken away permanently. The justice system has a long history of restricting peoples behavior who are (a) out of jail, but (b) still a danger to themselves or others.
If we as a society believe the person is still a danger, then we shouldn't let them out, ever. If that's not the case, then anything past their incarceration / parole is blatantly unfair.
