A fantasy of mine.
Many of those cameras are on aluminum cylindrical poles. All one would need to do is bring a nylon rope and a maul. You strike the pole with the maul, making a fairly significant crimp. You then lasso the pole and pull it down.
Or just use a paint gun.
These cameras and the light for the flash are monsters, and mounted on monster arms fastened to the signal column.
Your talking serious muscle to tear them down. Definitely would tear the rear bumper off of even a F350.
