Joking aside I think that you were right to report this incident imagegear. We all know of the ability of lasers to blind, if only temporarily. Ask yourself. Would we have walked away if both of us were blinded by this?
With Al-Quaeda being a real and present danger it pays to put this into the hands of the relevant security services.
Well done I say!
It may well have been kids playing.
...But what if it wasn't?
