They're no harder to aim than a gun at the equivalent distance, and you get the added benefit of continuous emission rather than a single shot (and no wind drift or lead). However, the tech specs for that laser show the "Nominal Ocular Hazard Distance" at which a 0.25s unprotected exposure does not cause lasting effects to be 149m. That's far, but not THAT far. So as long as the subject doesn't stare into the beam (which probably is more likely than you think given the brain's almost compelling instinct to look at sudden movements), you still have to get pretty close. (Unless you fit it with a collimator, of course.)
