Lots of people have been talking, over the last couple of weeks, about the problems of speed cameras.

It's an interesting concept and one which I think has a lot of similarities to the debate on marijuana.

They are both laws which have not been properly enforced because, mainly, the government knows that people wouldn't accept it. The key question is why there are laws on the statue books which the majority of people in society don't agree with.

Survey's are no good because people like to say that they are anti speeding and anti marijuana but actually what people mean when they say this usually is they are anti other people speeding or their kids smoking dope. The number of drivers who speed must be near 100%. And that means almost 70% of the population are outlaws. Living outside the law and hoping they won't get caught. Add in the number of people who aren't old enough to drive but smoke dope and the number goes higher.

So why do they remain illegal? If nobody really believes people should be punished for it?

The answer for speeding has to be that we believe that all people will naturally speed a bit so when we post a restriction we are really saying you can travel a bit over this number but not too much. The actual amount used by speed cameras is 10% +2. So it's only if you go above 79 Mph on the motorway that camera will photograph you.

And with marijuana it's something similar. Large numbers of kids will try one illegal drugs. And at the moment the most popular of these is dope. I don't believe it is a gateway drug at all, quite the opposite. The fact that people can be naughty but not that naughty is what is stopping lots more people dying from drugs that are easier to overdose on, on your first encounter with it.
