The "hurtful speech" Stasi at Missouri U

[GMTplus7]

@LasMa

So when the student body president was walking along, and a truck full of students slowed down to hurl the n-word at him…

This is what Missouri Students Assn. President Payton Head posted on his Facebook page about how a man on a pickup truck repeatedly called him a racial epithet while he was on campus:

Last night as I walking through campus, some guys riding on the back of a pickup truck decided that it would be okay to continuously scream [the N-word] at me. I really just want to know why my simple existence is such a threat to society. … I’ve experienced moments like this multiple times at THIS university, making me not feel included here.

Where does Head confirm these were Mizzou students?
