That works! The other thing nobody talks about is how cameras can be used for blackmail or for leverage. It could be a matter of catching someone doing something out of line, or more sinister, extorting money from a cheating neighbor. These are some of the reasons I find ubiquitous camera surveillance so insidious. There is infinite potential for petty abuse and chicanery. In a residential setting, they give busybodies and petty rule enforcers a very powerful weapon.
I'm pretty sure doing that to people is illegal or at least bad faith. In both my cases I never made threats but simply brought it to court. This also has the benefit of making the offending party pay a lot of legal fees.
