Thanks for sharing and being honest. Glad you guys are unharmed.
You did the right thing by walking away.
I'm curious tho how close did he get to you, that you had to walk around him?
IMO you should not let someone who can be a threat close to you.
If so you need to be prepared to defend yourself at all costs , I agree a 2700$ camera is not the best option but if the only one..USE IT.
O would from now on CC and try to always have another tool with you.
Anyway i'll get off my soap box.Seems like you have learned a lesson, and not the hard way.
