With all due respect that is far fetched scenario to say the least. How many times have you seen people elbowed in the head in nhb competitions? Lots! Who has died?

Good on you,but what would you have done if he didn't just walk away? What if he elbowed you back or worse?

A lady at work has pinched me inappropriately before,should I have elbowed her?
The2nd ammendment, it makes all the others possible. <///<
