Of course this is not a good thing. But to entirely prevent being “placed” at the scene of a crime you would never be able to carry a cell phone, drive a car, or even walk/cycle with your face visible. You’d have to leave and enter your house taking special care not to be seen by any cameras, etc

The point he was making is that if you want to entirely prevent any of these problems, the steps you have to tale are extreme otherwise you’re always leaving open a potential security hole.
