Having been one of those targeted, I reckon that trying to hit a cockpit doing 120kts, 2000ft above you with a hand held laser is a lot of hit and miss. I was able to pick out exactly where they where between the to and fro of the beam. Biggest problem is them being caught red handed. The defence case used in reverse would be - how could he, whilst blinded by the laser, really be able to accurately name the building and the backyard that it came from.
Just remember that if I meet you one day you will remember the full force of my law.
