All we know is he had a BB gun and got up to walk away after a cop told him to get on his knees or whatever.
What actions do you know happened that are 2 game suspension worthy? I think Rhoads does look at the whole situation and sees it for what it is, Nealy runs a few thousand yards for making a boneheaded decision (which didn't harm or put anyone at risk) and moves on.
At this point the only thing that he may have done that was an issue at all was IF he was one of the guys frisking people on central campus (who by the way they didn't hurt or take anything from). And even then it was clearly a BB gun they were using or they would have sent out an ISUalert because the gun looked like it might be real. They didn't.
Have you ever played paintball or lazer tag? They were doing that only they did it on ISU campus which was where they made the mistake. And as a freshman that hasn't been on campus long or gone through orientation or read all the rules for University property I can see why you would think carrying a BB gun with a couple buddies on central campus was harmless and wouldn't even realize it was against the rules.
My lord, I hope you're kidding.
