I have been 'pulled over' a few times as a result of handheld lasers
(LTI-2020)

The detector goes off 'LASER ALERT!' as the cop walks out to direct me to pull over - ie Too late.

The best course of action is to pretend your have been blinded by the laser as a result of it being aimed at your face. blabbing..."I have a migraine - black dots in my vision - I cant see!"
