OK guys, remember this was a completely HYPOTHETICAL QUESTION for those of you ready to put my mugshot on the post office wall. I was just having an argument with a guy about this possible scenario and was wondering what you guys thought

It is legal to keep any KY game fish in a tank(withou a permit) as long as it was taken legally and was of legal size. So, if the smallie was taken legally and was of legal size (from Elkhorn slot limit) haw could you prove that if you where turned in later?
