The number of reported incidents has been steadily increasing over the past several years. This could be twofold. More incidents may be being reported than might have previously gone unreported. The other reason, more and more cheap lasers available = more and more lasers in the hands of morons. The more incidents that occur the greater and greater the probability of a catastrophe. Either way, lawmakers may eventually propose a ban if the number of incidents continue to rise. They will definitely impose a strict ban if a catastrophe ever does occur. Morons make things bad for legitimate people.
