I would start by forcing judges, DAs, parole boards, and attorneys to assume some form of liability for the defendant if they give them a plea deal and they reoffend during a period of time they should have been in jail for whatever charges they dropped for the plea deal.

Plea deals are modified - a plea deal is no longer an intimidation tactic. The plea deal is not a 'negotiation', if the State comes with a plea deal it requires them to drop all charges they offer in the deal before presenting it. If this stops plea deals altogether, I'm okay with that too.

Vastly more crimes should be punished with execution. Burglary from a residence should be one of them. If we can shoot you when you're inside, we can shoot you when you're back outside. Just because I'm not home doesn't mean you wronged me any less. Car theft, too, just like we used to hang horse thieves. Drug dealing should also be execution - it's what they do in Southeast Asia and guess what, they don't have a fentanyl problem there.

Shoplifters lose hands at some point.

Illegal immigrants get their faces branded so everybody knows them when they see them. Multiple offenders lose their feet.

Exile should be reintroduced. For certain crimes, especially repeat offenders of low-level crimes, you can be sentenced to exile - all your citizenship documents are shredded. All your possessions are liquidated by the state. You're simply cast out to a random country with a facial brand.

Anyone giving succor to an illegal immigrant is a party to a crime, and anything they provided to them is considered evidence/criminal goods. If you let an illegal sleep on your couch, you lose your house. You employed them? Business is liquidated too.
