City of Phoenix has it all figured out. In order to curtail the folks who run the red light, they’ve installed cameras onto the overhead traffic signal. I’m going to guess that 95 percent of these are dummies (cameras not the folks). But, who can tell for sure? That’s the beauty of it. When the program first went into effect police took numerous photos and wrote citations. These early offenders were made public with high profile media coverage to boot. So now the other public is aware and camera shy. The (fake) black boxes sit high on their perches like psuedo Owls. Scare Crows.
Kind of like the school buses with cameras. Never know when they are recording or just sitting there taking up space! Most kids have gotten wise to the situation and are not intimidated by them any longer.
