Maybe it is disruptive, which changes the consider'ns. I did ask about that above. But laser pointers are not dangerous to eyes, unless you poke someone with one.

The hazards of laser pointers are limited to the eye. Although with most visible lasers, the largest concern is potential damage to the retina, most laser pointers are not likely to cause permanent retinal damage.
The most likely effects from exposure to viewing the beam from a laser pointer are afterimage, flashblindness and glare. Flashblindness is temporary vision impairment after viewing a bright light. This is similar to looking directly at a flashbulb when having a picture taken. The impairment may last several minutes.
Afterimage is the perception of spots in the field of vision. This can be distracting and annoying, and may last several minutes, although there have been reports of afterimages lasting several days.
Glare is a reduction or complete loss of visibility in the central field of vision while being exposed to the direct or scattered beam. This is similar to viewing oncoming headlights on a dark night. Once the beam is out of the field of vision, the glare ceases. While this does not pose a hazard to the eye, it can cause serious distraction and outrage. Glare can be exacerbated when the beam is reflected from a mirror-like surface.

More Laser Safety
Maybe there's little risk of permanent damage to the eye, but there is real risk of injury to the player due to being distracted on the football field and they seriously compromise the fairness of the competition when the quarterback is unable to see clearly for several minutes.
Fans can do lots of things in the stands. One thing they can't be permitted to do is directly interfere with play.
