While this definitely does not fall under the category of a prank video, the social justice of it is phenomenal.
The premise of the "prank" is that a long piece of paracord is attached to what would appear to be an unlocked bicycle. When a thief tries to steal a bike, they end up face planting in the dirt. The only problem I have with it, is that each thief got away.
If they decide to do this "prank" again, I think they should have one or two officers around for the arrest.
