Not to be too arguementative but I fail to understand how some of you guys are thinking that you can make a 100% clean "getaway" if you are in a car...
If you are on foot then maybe...
All it takes is a nosy neighboor type and a plate # and you might not even make it home before seeing cherries...
I dunno though, that's just me... Anyways, to the original question...
If the situation forces me to draw and he runs...once there is no immediate physical threat, I'm hightailing it back to my car and getting the hell outta there...perhaps even to a well lighted, public place to calm down for a minute or 2...
I think, dependingon the circumstances, I personally would at least call 911, relay what happened, mention that the danger has passed so you don't really need an officer to respond and finally ask the dispatcher if it's worth even making a report...
(however unlikely) If the answer is no...Then listen and don't bother and at least you have some sort of record of what happened and which side of it you were on...
and (more likely) if the answer is yes, then filing a report is 100% voluntary and should you choose not to go in and file a report, you still have that record of what happened should it come up again...
Although probably not the most realistic scenario of what actually would happen after making that call... anything more is on the dispatch/officers IMO... you stated it was not an emergency despite calling an emergency number and simply wanted them to know in case a 2nd party madde a call...If they choose to respond, then that is their business I suppose... All you can do is write the report and give your description at that point... I can't really see the police trying to charge you with anything...Just know the letter of the law (and conduct yourself in accordance) and be mindful of your statement...
The long and short of it is this... do whatever you feel is best and abide by the consequences of that decision...
or just ask a local city cop what their take on it is..
