What I want is quick trial and immediate execution for murders with malice: most are obvious, after all. If they aren't, they can be held till it's sorted out, and self-defense is not charged, of course.
I also want quick trial and immediate execution for any malicious injury, attack, or stealing or robbery --- say worth over $1,000. England did that until the 18th century, and it sure did clean up that gene pool.
Reminds me of many years ago when an empty store around the corner from me was reopened by a middle-east family. Since it was a minute walking distance, I started to shop there and got to know the people.
One night I walked in and the police were leaving. I asked the young clerk what happened? He said some drunk walked into the store, took six packs of cigarettes off a display sitting on the counter, and walked off. He was in disbelief that the police did nothing about it, except say to call them if he comes back, and they'll kick him out of the store.
He said after they opened up the store, his grandmother in the ME wrote to him asking how he was getting along. She asked about his new environment. So he returned to her a local newspaper we had at the time. He said she wrote back with great concern. She stated that we have more theft in our suburb in one week than the entire middle-east has in a year. I asked him if that was true, and he concurred.
He said where he was from, most vendors were outside. They setup picnic tables with umbrellas so the potential customers could rest while shopping. If a woman lay her purse on that table, walked away forgetting about it, it's more than likely it would be there the next day.
People would cross the street to walk on the other side so they didn't go near that purse. Because if you got caught stealing, off comes your hand, and not in a hospital either. Get caught again, off comes your second hand. There is no third time.
That's why we have so much theft in the US he explained, and no theft in the middle-east.
