HotI can I ask why you flash at speed cameras but not booze buses?
I don't agree with drink driving at all. There are many steps that lead to a person driving after drinking, and at each point they are the decision that they will drink alcohol and then get in a car. e.g. they take their car to a place where they know there will be alcohol, they order alcohol & drink it, they decide how much they will drink (knowing they have their car), they decide not to take a cab or get someone else to drive, they get in the car & drive...

People who are over the limit, or close to the limit (or maybe affected at all??) shouldn't be driving and i am not going to do anything to stop them getting caught.

I don't see speeding (doing small amounts over the legal speed) in the same light at drink driving. It can be non-intentional, and if them seeing a flashing light makes them slow down then the reason for speed cameras (to deter speeding) has been achieved.
