A slang term referring to a police badge, glamorized on many shows such as CSI as a "pass" which can be flashed to gain access to restricted areas.

This term has been used - but doesn't necessarily originate - on an episode of CSI: Miami.
"Beware, that area of town is closed down now."

"No worries, I've got the brass pass..."
