Not really. Apparently it's not all that dangerous to shine a laser into a helicopter, because rather than attempt to escape and control his vehicle, the pilot was able to catch the offender by staying in flight and locating him by following the source of the light. This allowed ground personnel to come in and arrest the offender. It's conceivable that it could be dangerous if it happens at a very inopportune time for a pilot. So far, though, nobody's ever died from laser pointers shined at cockpits.
