I don't care if he put it in his pocket assuming he had a license. I wanted a gun then because he stared at us angrily and returned to his car to get something. I've been raised to read body language and they were some strong signals he was throwing off. I wish I had had a gun in case he had pulled and and started shooting or making demands. If not there would be no problem. That is all I was saying and I don't think your reading into it makes the situation any more helpful for anybody.
If you rear ended me I'd be looking at you angrily.
I may even reach into my car to retrieve my phone to take pictures.
I may even begin to yell at the driver who is an idiot for not keeping a safe distance.
None of those things would give you reason to brandish a firearm.
