SLED POLICE — with radar guns. I agree with the commenter who says, “When cops start this kinda thing, it’s time to start laying them off. They have way too much time on their hands.”

UPDATE: Orin Kerr thinks my provocative headline is misleading. I guess he’s right, though I saw the story as evidence of creeping nanny-statism, likely to produce a slippery slope leading to mandatory helmet laws, actual speed limits, etc. Plus, who didn’t know that sleds can go 19 miles per hour, roughly as fast as a man can run? This seems to be how most of the commenters at Don Surber’s blog, linked above, saw it too. We’ve been down that slippery slope in plenty of other areas, and we didn’t need a sled to do it. But to the extent my pithiness was misleading, I apologize. Meanwhile, Meryl Yourish has thoughts that I hope are tongue-in-cheek. Er, can you do that while wearing a mouthguard?
