And in reading some posts on "that other site" where some members actually attend Purdue and some have had classes with the TA that was killed this was a planned homicide.
Apparently the TA had quite a reputation for being an asshole to the students in his classes. It sounded as if he was vindictive and willfully failed students he did not like, even though their academics were acceptable.
How would you like to find out your scholarship was cancelled because a dick head TA failed you out of spite?
Actions have consequences. On both sides of the coin.
