Good points, again as we don't have CCW here, I hadn't thought of all the possible scenarios.
The down side also could be, that you were correct in your assessment of what was going on, and you run off and find later you had just witnessed an innocent person get murdered. AND, you did nothing to help.
I know, it's not "your job" and your very correct in the reasons given for not intervening. Would be a very tough call for sure.
Our city, is seeing more and more assults & robberies, in broad daylight also.
Two bikers got mugged yesterday on a bike trail, good news is they are alive today!
Thanks for your thoughts on the issue!
