I think that any investigation into a cockpit lasing event would soon ascertain whether it was an accidental strobe by someone using a laser for astronomical purposes or "chav scum" having some sport.
How difficult can it be to issue a laser license to those who have a legitimate reason to possess such a device?
How many ac have been brought down by lasers in comparison to negligent engineering driven by cost and time cutting practices?
