i hear that they are popular in russia but it is because of the high rate of people trying to gain false insurance claims from "accidents" that they have with you
Yes, this is a growing issue in Russia, and my husband and I, though in the US, are increasingly concerned about the idiot drivers around us doing something stupid or intentionally that could be "faulted" to us. If you've seen rush-hour video of someone backing up in traffic, bumping the guy behind him on purpose, getting out and saying "we can do this without the cops or insurance if you give me $500 cash right now" then yeah, i'd say they're a good thing.
Legally in the US, you can film just about any public place without signing anything as long as you aren't targeting strangers' faces.
Public areas are public areas. You should assume that someone is recording you anytime you step off your property.
It makes people feel like they're doing something to protect the children. It's a placebo.
If the reality of people opting to put band aids on problems instead of solving them bothers you, it's hardly my problem. The simple fact is the US government records your and your child's phone calls, text messages, and anything transmitted online. If it bothers you that some people have cameras on the dashboards, you're in for a heart attack when you take the time to investigate how this modern world works.
London is the most recorded city in the world with hundreds of thousands of CCTV cameras inside and outside public buildings. The US government records the phone calls in the UK too. These are major news stories.
Cancer in any part of the body is a cause for concern.
If one is somewhere where anyone else could be and see you without otherwise causing concern or suspicion, there is no reason they should not be allowed to record there as well.
I am comparing the government spying on its citizens in only a small part of a country to a cancer growing in only a small part of the body.
