If you're just trying to avoid regular everyday tracking, those may work. But if you're trying to actually get away with a crime, the problem is that you're trying to avoid every camera in a city, not just the flock camera you're vandalizing. Your neighbor across the street could have a ring doorbell that records you every time you walk out your front door. You can have the most elaborate disguise you want, but if there's video of you walking out your door wearing it, you're busted.
