Well, according to actual witnesses (see what i did there?), after it happened, LeBron went over the Nike rep, said a couple things, and then the Nike rep immediately went to the two people in the gym who were filming.
A couple things, had the person filming been me: I first would have argued that it was my (son/brother/friend) playing and that it was a moment I wanted to keep with me...and if that didn't work, then they could have the tape for a cool 200k.
Edit: Also, they mentioned this on PTI...who the fuck films on tapes still? I would have been filming on my HDD camera, then what would they have done? Slammed my camera on the floor?
Thats fine if there was some evidence
It came across like he was just pressuming it
