Donald Trump must be getting desperate. His latest proposals are ridiculous. He has proposed letting police department have a day on violent retribution against those they consider to be criminals. It is insane!
It's also unconstitutional. The Constitution prohibits cruel and unusual punishment, and allowing the police to attack people without arrest or trial would certainly meet that definition.
It's also illegal. It is against the law for anyone to attack or abuse someone - including the police. In fact, because of the power we give police officers, they should be held to a higher standard.
And finally, it simply would not work. It would not eradicate crime as he thinks. I worked in various aspects of law enforcement for nearly 30 years. I never met a criminal who thought he would be caught. And if someone doesn't think he/she would be caught while committing a crime, arrest or violence would not serve as a deterrent.
This would not make our society better or safer.
