I found this article that explains the danger. Beaches are also heavily populated areas in the summer time which increases the risk and not everyone can qualify for the Coast Guard because it is dangerous and they lose people.
If any aircrew member’s vision is compromised during a flight, Coast Guard flight rules dictate that the aircraft must abort their mission. Laser pointers can cause the pilot to see a glare, afterimage, have flash blindness or can even cause temporary loss of night vision.http://www.capemaycountyherald.com/arti ... er+pointer
Additionally, aircrew members are taken off flight duty for a minimum of 24 hours and must have their eyes dilated and be cleared by a doctor before flying again. This temporary loss of crew has the potential to significantly affect the unit’s abilities to conduct search and rescue, training and homeland security missions.
The Food and Drug Administration regulates the manufacture of laser products and according to an FDA Consumer Safety Alert, overpowered green laser pointers may have been modified to emit more radiation than originally intended. These overpowered green laser pointers are a serious concern because they can cause permanent eye damage.
