This has been a problem at airports ever since these laser pens became widely available. There no way to catch whoever did it unless someone witnesses them doing it and goes to the police - the beam could be coming from absolutely anywhere in a fairly wide radius. There's no way to trace exactly where it came from.

Needle in a haystack I would say. People would need to be caught in the act. Personally, i think laser device usage should be regulated and controlled, but there is already a vast number imported from other countries, so the horse has already bolted.

I remember kids shining them in people's eyes at high school. Luckily no one that I saw suffered any real harm but I wouldn't be surprised if there are kids out there who have had their eyesight permanently damaged by some stupid kid shining a laser pen around.
