My theory for speed cameras; Part 1!

[XDV800]

Speed Cameras. 2 issues i have with them.
Some of you feel enraged just at the thought of the bloody things sending you a postcard in the mail, i know i do.

Theres always a discussion about these things and how they are simply a way for the states to scavenge as many dollars from us as possible. Families, low income earners, volunteers. Some people could be left on their knees if their licence is taken away from them. It really is an attack on our rights as citizens to live in a democracy, where innocent until proven guilty is supposedly an ideology upheld by the court systems.
So how did the courts and the lawmakers and legislators in whatever superpower country that 1st introduced these devices, decide that it was ok to fine and infringe penalties upon people, for basically committing no crime, no harm to any fellow human being, or property, but simply operating a motor vehicle at a speed at which it has been designed to achieve, and then happily sold to the public to use in any way they see fit.

Lets face it, being ticketed for speeding is just an ASSUMPTION that an incident may occur. How can we justify this seriously?

(I am creating a Part 2 to this to highlight my thoughts on my 2nd issue, and a new approach on camera locations and who controls them. Just didn't want to have all this in one thread)
