what does lasting 30sec have to do with it? how long would it have lasted if Colie hadn't pulled a gun? how many more times would have have been threatened? And yes he was being threatened by a 6'5" man continually advancing on him.
Remove the gun from the equation; what if Colie had beaten Cook instead until he felt safe again and put him in the hospital ? Would that be justified since it didn't involve a gun? Same result either way.
you need to forget about the fact that this was a prank or what Cook's intent was. They have no baring. Only what the real victim (Colie) perceived; and Colie felt threatened and had every right to defend himself. The fact that the means he used was a gun is an entirely different topic of conversation. He felt under threat as any reasonable person would in that situation.
Yup. I'd love to see an analysis of his victims. How many 6'5" grown adult men of reasonable physical build does he try this shit on? Maybe a nice histogram of height vs. prank count. I wonder where the data points will end; hmmm?
