Sistilli released a couple of YouTube videos showing his homemade ALPR to track police cars. It wasn't actually very effective. It only correctly identified two out of seven cruisers that passed his location during the hour he tested it, and it did not capture the license plates of either one, which is about as reliable as a real Flock camera. Still, that was enough for several Peel Regional Police officers to pay Sistilli a visit about his cop-detecting ALPR, even though he'd done nothing wrong.
