Are police check points illegal?

1. Being stopped is not a search.

2. Drunk driving is a crime, even if there is no injury or property damage.

Nope. The whole point & purpose of police check points is because the cops are looking for someone or something specific.

It might be a fleeing fugitive. Or an escaped prisoner. Or they're just trying to get some drunk drivers off the roads.

Regardless of their reasons for it, it's just tough sh*t on you if you don't like law enforcement doing its job.

ALL traffic violations are crimes.

Checkpoints are legal and being on PUBLIC roads is legal cause.
