I wonder how much of this is malicious and how much is just dumb teenagers? I could definitely picture kids playing "I wonder if I can hit the moving target" while having no idea how what appears to be a tiny beam of light can light up a cockpit. I know it's been on the news lately, but how many kids watch the news?
I would hope that these things are being sold with a huge warning on the box about not pointing them at moving vehicles.
