I have a reasonably powerful (I think legal) green laser; it lives in my jacket pocket, I find it extremely useful when giving presentations or pointing out things on an aeroplane on my regular periods in the hangar talking about modifications and problems.
So, don't please pressure to ban a very useful tool - just ensure that the misuse of that tool is a criminal act that is severely punished.
With all due respect, there is NO need to have a "green reasonably powerful laser" as a pointer. They should be limited to red only so less powerful.
Anything over 5mW should require a licence, there is no justification for the general public to have access to anything over that.
