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."
term used to describe an inept group of people for their mistakes and/or lack of coordination and/or inability to get things done. Comes from a series of silent movies made by the Keystone Film Company between 1912 and 1917 about a group of incompetent policemen and their various escapades.
I don't know about you, but in the past few years, it seems to me that every time there is a major crisis, the government runs around like the Keystone Kops!
