So at what point do you stop making a potential victim responsible for what the potential offender did? He had no idea what the guy was up to.... other than what the guy may have said which we don't know yet. Like so many other cases... Lots of folks like you are looking for ways to go past the facts we have.
I'm going to say I'm around 99% certain that the guy didn't just go in the wrong door, say, "Oh crap, I'm sorry", then leave. If that's the case then JM is in for a bad deal. Football is the least of his worries.
However, that doesn't seem very likely. What he said, did, and even said he did... matters.
Why are so many like you intent on convicting someone without knowing all the facts first? Even if it was an "actual mistake"... what the guy did before and after the "mistake" matters a lot when it comes to JM's culpability.
So you have all the info and have already convicted McCullough? No. You don't. You have one side and some media spin. That's what you have. And you want to lecture someone else about what's right in this instance?
