I suspect that the law cited by Devil's Advocate is the very minimal charge that could result from pointing a gun at someone. Under any circumstances, no matter what else is going on, it is at least a misdemeanor just to point a gun at someone, whether it is as a joke, a threat, an accident, whatever. The existence of that law gives a very easy way for a police officer to put a stop to some bad stuff without having to establish probable cause for anything except pointing the gun.
I further suspect that pointing a gun at someone and saying, "Don't move or I will kill you", is a very different, more serious, crime, in addition to pointing the gun, and also pointing a gun at someone in such a manner that a reasonable person would think that the threat is implied is also the same, more serious, crime.
ETA: I see that the law says "intentionally", so I suppose "by accident" in the above is incorrect.
