"From New Jersey to Utah, pilots are reporting incidents of laser beams aimed into cockpits during flights. In a few cases, pilots were temporarily blinded before recovering sufficiently to make safe landings."
What the article fails to point out is that the cases where pilots were temporarily blinded all appear to have involved commercial industrial strength lasers (the kind used in lightshows) not the small, hand-held pointers. A terrorist hauling around one of those is bound to attract attention - it's not something you slip into your pocket, or even inside a suitcase, I understand. Even in those cases, only one pilot was affected, which means unless you're trying to shoot down a small, general aviation aircraft, you're likely to be wasting your time. And you're not going to go unnoticed.
