This video is from a year or so back, but it’s a great educational tool to ask the question: What would you have done?
I am unsure whether the man being leadjacked was carrying his firearm on him, or if it was in his car. Either way, he was able to quickly retrieve it and fire at the bad guy.
I wonder though, did he see the guy coming up to his car in his side-view mirror or was he not aware of his presence until the leadjacker’s gun was in his face?
