Wow. Your single anecdote showing humans have created an imperfect system, and/or sometimes some people just don't want to live in society with others no matter what, once again has really shown me that we should only ever go after the symptoms instead of working on the real problems. More police! More jail time for everyone! Death penalty for minor offenses! More jails need to be built! Surely that will fix it this time!

That was sarcastic in case you couldn't tell.

Domestic abusers need to be in prison until they can decide to stop being an abuser, full stop.

Likewise people who abuse welfare benefit programmes and steal food from their own children in order to trade it for cash.

There is simply no excuse for that, period, and it doesn't help anyone to tolerate it or be lenient on it.
