With cheap, tiny, multiwatt pointers - it was only a matter of time before some idiot pulls this dangerous little stunt. I think it has already happened at soccer matches with what looked like 532nm. This incident looked like 520nm to me.
"The NFL is attempting to shed light on who allegedly shined a laser pointer at Buffalo Bills players at Detroit's Ford Field last weekend."
