you do know the police and the university or two separate entities. School cannot release anything without consent but obviously police jurisdiction takes precedence and if hanging a noose is a crime then you might get his name. Outside that the school is not allowed to release the name.
Now the fact that he admitted to it, more than likely it may be leaked.
it's similiar to this, where white hispanice girl went on twitter and called a black blogger the n-word. I was emailing local news stations and barry regarding this incident to try to push coverage on it. Either way, the girls name was not only known (obviously because of her IG/twitter handle, but her family was figured out and also that she went to Barry). So, the school was forced to investigate but obvously did nothing and her family business (her dad is a famous Dr. in Miami) was also put out there. Is that fair? Maybe - but this double standard you guys are talking about , while it does exists , isn't 100% exclusive to blacks.
