In regard to certain cities granting some sort of protection for criminals: This is not new. Many cities in the U.S. extended protection to criminals if they did not engage in criminal activities in their city. The local police would look the other way.
This was common in the 1920s and ’30s. John Dillinger lived in St. Paul, Minnesota, for a period of time. The FBI almost caught him. He escaped in a hail of gunfire. Mr. Dillinger had been tipped off by a local policeman.
For many years, there was little love lost between the FBI and local police.
