I am in no way saying that its not possible or that the miscreants should not be "seen to" but......
Some little scrote with a hand held laser pointer is going to be lucky to get his beam the length of a football field. Even if he does manage it, he has to be in the right place with the right elevation with a very steady hand to actually hit someone on the head in the cockpit when the pilots are sat back from the windows.
Even more lucky to get them in the eye which, as has already been pointed out, has a diameter of less than 10mm.
So from a distance of a couple of miles, allowing for the angle they would need to be at, they would need a military grade guidance laser on a steady tripod.
There is more to this story than is being published. Some of it, unfortunately looks like some pilots are swinging the lead a little. Maybe they did see a laser spot in the cockpit but it is almost impossible to actually have been hit in the eyes with it. It certainly doesn't happen for real as often as it is being reported.
That said, as I said at the beginning. The scrotes that shine the lasers at anything other than their own eyes or a whiteboard need to be "dealt with".
