Upon further reflection...

On the night of St. Patrick's Day, law enforcement officers in Montgomery County, Texas, set up a DWI checkpoint in The Woodlands -- at the base of an overpass.

After stopping a citizen suspected of driving while intoxicated, officers asked a wrecker driver to park on top of the overpass with his lights on to warn oncoming motorists. Shouldn't this have been a sign? In fitting irony, another motorist, who was subsequently arrested for DWI, slammed into the back of the wrecker, injuring the wrecker driver.

Perhaps the officers who made that decision should have had their blood drawn to determine if they were under the influence.
