You guys are over-****ing-exaggerating. He wasn't okay with someone getting all close to him and he clearly wanted him to get away from him. That was not an attack, he didn't even look mad, just annoyed and frustrated.
That reporter shouldn't have done that. Do I think he should've slapped him? No. But it wasn't at all hurtful and it certainly wasn't uncalled for. Will wasn't in the wrong.
