I've grabbed a screenshot of Mr. Sweet's comments and will be sending it as an attachment to those senior members of the faculty and administration at Arkansas State University whose titles indicate that they might have an interest in his sentiments or might play some role in allowing him to return to campus.
To the president of the university I will be sending a separate email that includes links to Mr. Sweet's numerous posts all over the Internet boasting about having created child pornographry that included an image of one of the president's predecessors.
If I'm lucky, Arkansas State University will look with disfavor on an alumnus who brags about committing and intending to commit multiple state and federal felonies in a scheme that involved inserting an image of one of the school's former presidents into a sexual situation with a child. Universities have been known to revoke someone's degree for far less.
If I were you, Mr. Sweet, instead of gloating about Ms. Thrasher's death, I'd get busy pulling down 17 years's worth of boasting about the heinous felonies you've committed, the blatant libels you have posted and the death threats you've made. If you move fast -- I'd pay to watch that! -- maybe you can avoid a visit from the police.
