Perhaps there are enough people to solve crime AND ensure the government follows the laws passed by elected representatives of the people.
I thought there was a law against murder. I don't remember electing any of the cops in my city. I do remember the elected attorney general and judges refusing to press charges. Perhaps there are enough murderers?
You didn't elect the cops, and yet they're apparently violating laws meant to protect you. If you don't want that protection, consider voting for representatives who will pass fewer laws.
