Speed cameras

I really hate the idea of those cameras that take pictures of your car and measure your speed at the same time. If you're going too fast, they send you a ticket. Illinois State Police are using the system in work zones -- I admire enforcing speed limits in work zones, but this just doesn't feel right. It becomes too easy to issue tickets and too difficult to defend against them.

There's a company that sells a spray on coating for your license plates to avoid detection when it comes time to take pictures. I don't' know if it works but I don't think it is illegal.

It's called Photo Blocker.
