Self defense.

If you feel physically threatened, use force.

You are allowed to defend yourself, if you feel threatened it is well within the law.

When he is thus distracted, draw your weapon & have it ready, just in case.

I have only had to do that once (so far) I had the State Troopers on the phone within seconds.

They came out & they had some very stern words with him.

They told me 'Well done.' & away he went.
