Honestly, that is probably better. Kinda like never pointing a gun at anyone, whether you think it is loaded or not.
Put another way: I don't trust many H&E techs to know the difference between an SX GBIC and a Buck Rogers Laser Cannon.
Besides, lots of lasers these days are infrared, so you can't see them anyway. (Hence the "last thing you never saw" comment.)
