I have heard certain folks say that in a tactical situation where a gun has a "light" trigger., where adrenaline is running high, one runs the risk of an accidental double tap or stray shooting. I don't agree with this notion and agree with the statements made above, if you know how to handle a firearm properly and when to shoot and when not to, a "lighter" trigger is not going to be an advantage or dissadvantage per se, but having said that, obviously the law enforcement community does not really agree with us, hence the popularity in part of the DAO Glock trigger at 5lbs+++, but of course they don't study these things on the level that we do, to them its a lethal tool.
