Police ought to be licensed, like airplane mechanics

18. Sounds like this is fairly common.

That this could have been found out fairly easily.

And doesn't have the result you claimed it would.

Perhaps because people don't know there are real requirements or certifications involved, don't make the effort to find out, but assume that if they don't know about them then they don't exist.

BTW, teachers are also certified. Most of the time during a review they're absolved. Not always. But "not absolved" doesn't always rise to the level of firing them.

Often it's also easier to give them a good review and tell them to push on than go through the hassle of firing them. Teachers are protected against vengeful administrators by certain regulations in pretty much every state. However, if a teacher is fired and loses his license, often he could head to another state and get certified. He'd have to commit perjury and deny he'd been fired, but there's no consistent national-level system for tracking these things.

The US was set up as a federation of states. To some extent the central governing authority has centralized even more authority, but there are still large areas where the President isn't in charge of every person in charge of every aspect of our lives. In other words, where there's varying levels of local control.
