I'd bet that 90% of the cases aren't even people trying to be malicious. Just some dumb kids playing around with one of those cheapo $10/50mw lasers off ebay. They think it's cool or w/e when they realize they can hit planes with it and they don't even think of why it might be bad. This is an inevitable consequence of the falling price of powerful lasers.They need something to talk about. Simply shouting the word "Sensationalism" doesn't seem to work for some reason.
But yeah, just don't point at aircraft. Why are there idiots still doing this?
