An example needs to be made of idiots who this sort of thing. It isn’t the pilots life being endangered it is the people on the ground who may get killed if the illegal actions result in a crash.
There should be a high visibility trial and the maximum sentenced imposed. Perhaps that will deter the next moron who thinks doing this is funny.
I wonder if the guy wasn’t using the laser to scribe a line on a wall or some thing like that . Maybe forgot to turn it off?
