Any good cop who wanted the right answer could find it if he looked, but that wasn't the point.

What if a cop had found an excuse to search him?

He was trying to figure out what might happen if the cop found him again.

The cops didn't find an address book at 756 Maple.

The cops found his calling card at my mother's house.

Given enough time, the cop would work his way through the mirrors and find the man.

I don't want the cops to find me talking with you.

A few minutes later, the other cops find Luis in his car, dead.

The cops had found what was wrong with the engine.

I expect the reason the cops haven't found him is he's dead.
