http://www.youtube.com/watch?v=5F4YCXDydFA&feature=related This is a serious question. Some of you have seen this already. I am curious about the use of force issue here when the enraged dentist forces himself into the other man's vehicle. Now, in this circumstance, he got out and yelled at the man to move the vehicle. But, a vehicle is a deadly weapon. If someone is trying to hit you with their vehicle, you can reasonably use deadly force to stop that person. This dentist was unarmed. But he was clearly enraged and unpredictable. There is no reasonable expectation that he wouldn't have used that vehicle as a weapon when he first got in (maybe kicked it in reverse or in drive, smash another vehicle or person, etc.). The dentist forcing himself behind someone elses vehicle is akin to him trying to grab a gun or a knife, really. So, at what point in a circumstance like this would it be justifiable to pull your firearm to stop the use of a deadly weapon (in this case, a vehicle)?
