Mostly because we have almost no proof that cameras actually deter anything, it's just intuition.
If I had to guess, burglary happens due to economic factors. How rich are you compared to the people around you. If you're extremely rich and everyone else poor, then yeah, you're gonna be robbed. If Elon Musk moved into my neighborhood and built a 100 million dollar mega mansion, he will be ransacked. He'd have to put up fences and have armed security. That's why he doesn't live in my neighborhood.
In the worst case, you're paying the privacy cost for... nothing. You prevent nothing.
In the best case, you prevent some thieving.
So, I don't know where it lies. We need controlled studies on this for sure, not just intuition.
