Texas police accidentally do something useful: Gardening.

Corpus Christi cops in Texas mistake actual weed for marijuana, spend hours doing yard work.

"one of the largest marijuana plant seizures in the police department's history," turned out to be a common prairie flower of little significance...

Texas officers ultimately spent hours laboring to tag and remove up to 400 plants from a city park, discovering only after a battery of tests that they had been sweating over mere Horse Mint, a member of the mint family.
