How does the real cop figure out he is dealing with an impostor?

[dragnet2]

Wrong terminology, not following standard police protocol regarding traffic stops, cheesy or no ID, no badge or fake badge, wrong uniform, equipment not used by law enforcement or that jurisdiction etc.

It all adds up to Sum Ting Wong.

If you’re a real cop it’s pretty obvious. You get familiar with local agencies, their people, what equipment they use, what equipment they don’t use, etc.
