I was reading the LP forum and people spoke about receipt checkers who would physically block their path.
I have a huge issue with my personal space being violated. If someone where to physically block my path and then not move when I demanded I would assault them. I have had people grab/touch my shoulder to get my attention and I unconsciously immediately swing on them. I have been training over the last year and I now know I would likely connect if I swing now.
I know most states have legal protection under shopkeepers privilege. If I am not lifting, someone attempts to detain me, and I assault them what legal protections do I have?
