I don't think this is nearly as big a deal as a lot of people would like to make it. What Martin said and what George heard may have been 2 very different things - remember that George was having his head beat against the ground. Martin may have said something like "You shot me!", while George's ears heard "You got me!". That one statement in isolation makes very little difference as long as the majority of the evidence lines up with George's account of the incident (which so far, it does).
“You got me”...Heard it a hundred times when the kids were playing their video games. It comes with sound effects, too.
Yep. ‘You got me” sounds alot like ‘you shot me’.
