Are law enforcement cameras an invasion of privacy?

[Rydrum]

The only time you really lights and siren is to clear an intersection when there's traffic. Otherwise all it does is cause people to panic, slow down, change lanes erratically and stop in the middle of the road forcing you to take evasive action. You're better off just blasting through as fast as you can. When they don't know you're coming you can get by them faster. If there is heavy traffic you don't have much choice but in light traffic you're better off without them.

That is really interesting, and good "did you know" type info.
