What is the law and order sound?

Tom Shales in the Washington Post says "Plink-Plunk."
The South Bend Tribune says "Ba-bing!"
The Arkansas Democrat Gazette says "doinkdoink"
The Pittsburg Post Gazette can't decide whether it is "chung-chung" “bong-bong"
The Boston Herald says "ching-ching"
CNN says "Chik-chok!"
The NY Times says "Cha chang!"

I saw most of the first couple episodes of the Trial by Jury spinoff. It seems pretty good to me.
