Professor Scott Senjo was a professor of criminal justice at Weber State University in Ogden, Utah. Twitter published the man's bosses info and suggested his boss be made aware of his posts.  Professor Senjo was subsequently fired from his teaching position after push back from Weber students. 

By the way, this kind of thinking from those involved in law enforcement does not surprise me in the least.  Law enforcement, like its military brethren, have to de-humanize those they oppose in order to kill them.  Its common for cops to think of those they police as less than them and give them names like "towel heads" or "porch monkeys."
