Why wouldn't they be fair chase? They weren't baited or trapped. It was coincidence that tey were locked together. I know it's not the most sportsmanlike way to get a deer, but I still think that technically they might be considered fair chase. I don't know all the fine points of fair chase, so i think I'm going to get educated in the next few posts.
Go ahead, I have my flame-retardant suit on.
HAHA.
