What did someone say to a cop that immediately incriminated them?

My father was a cop for many years and one of his favorite arrest stories was when he pulled

someone over for simple traffic violation.

I think the guy in question didn't do a full stop for a stop sign.

When my father asked, do you know why I pulled you over?

The gentleman responded, yeah, yeah, it's because of all the substances in my trunk. After my father read him his rights and was putting him in the back of his car, my dad asked, just out of curiosity, how did you know I knew you had substances in the back? The man ushered to the radar detector in the front and said, I saw the substances detector on the dash, and I knew you had me. My father still laughs about this one 20 years later.

I was sitting in my patrol car watching cars drive by one night and I see a four-door car drive by

and see it has a tail light out. Now usually I just stop the vehicle and let them know that it just

needs to be fixed, so I turn on the old cherries and berries. We go through procedure.

Hey, I'm Officer Corb with the police department. Do you know the reason I'm stopping you? Um, is it because I'm wasted? I was very taken by surprise. Why don't you go ahead and step out of the car for me? I'm not a police officer, but I got pulled over and I thought it was because of an illegal U-turn I did.

And as the cop goes,

Do you know why I pulled you over?

I sheepishly responded, it's because I did an illegal U-turn. He kind of just stared for a moment and switched on my headlights and said, Your headlights are off, and stop doing illegal U-turns. Oh, I'm the idiot in this situation. And being apologetic by nature, when I got pulled over for rolling through a stop sign, I said,

I'm so sorry, officer, I'd do it all the time.

Man was beaten unconscious by three men.

I caught one of them escaping on foot, but he vigorously denied any knowledge of the

incident.

Another officer who had collared someone he thought might also be

involved, unfortunately had little evidence other than the fact that the guy was running away

and he couldn't really account for his presence. The other prisoner was being taken to a cell

just as I walked into custody with mine. My prisoner looked at the other one and immediately

yelled, Matt, Matt, Matt's got nothing to do with this, you should let him go,
