Pennsylvania State Police.

Taken from both the silent comedy movies of the same name and that Pennsylvania is the Keystone State, using the keystone as one of its symbols (which is found as the dash separator on their license plates as well).
"Slow down - there's a Keystone Kop sitting up on that bridge!"

"PA has a nice state law - only the Keystone Kops can use radar. Local police can't."
