Long time lurker, first time poster here.
The local feral 'yoof' have taken to mucking about with at least one of these gadgets - having been 'hit' from the other end of the street the other evening I realised for the first time how much of a hazard these things are ('hit' from about 400yds away, side on to the beam and dazzled for several seconds afterwards).
As I live only a half mile or so from the flightpath of aircraft on final approach to Edinburgh airport I did my civic duty. Sadly, experience of the local plod leads me to believe they won't pursue incidents of this type until they are fishing aircraft parts out of the Firth of Forth
IMHO pointing one of these things at an aircraft (or any moving vehicle) should be treated as attempted murder.
