The “noose on the statue of James Meredith” incident occurred in 2014, but the court case took until 2016 to finish. http://thedmonline.com/former-ole-miss-student-austin-edenfield-sentenced-to-12-months-probation-for-putting-noose-on-james-meredith-statue/
The other incident occurred in 2016, as did the administrative actions by the fraternity chapter and the university.
Of course, incidents like these poison the state of race relations. The university’s nickname and mascot, and the state flag, are not helpful either.
