Seung-Hui Cho was the murderer who killed 32 people at Virginia Tech, before killing himself.
Incident with professor and class
In a email complaint by him, Cho complained about one of his professors, Nikki Giovanni, at Virginia Tech possibly because he perceives her as a bully. Cho wore sunglasses to class cover up himself, possibly in response to the perceived bullying.
His sunglasses made Giovanni to perceive Cho as the bully.
Giovanni became angry at Cho for not taking off his sunglasses, her anger might have been interpreted by Cho as bullying.
So she confronted him about the dark sunglasses and maroon cap he would wear in class and the darker poetry that he would write.
“You can’t do that,” she told him, referring to the “intimidating” poems.
“You can’t make me,” he replied.
“Yeah, I can.”
Her next step was to lobby the department head, Lucinda Roy, writing a letter requesting he leave the class, she told CNN. And she was ready to go all the way.“I was willing to resign before I would continue with him,” she told CNN. “It was the meanness.”
In his email, Cho said "You can't make me" because in the beginning of the semester the professor said that "it would be nice to take off your hats but I won't make you." Cho only said that because he really believed the professor can't "make him" because she said that earlier. His professor might have misconstrued Cho's response as an act of rebellion against her.
Cho filmed Giovanni, possibly to expose her contemptuous behavior towards Cho. However, a few female classmates complained that he was filming them. One female said that he was filming her legs. Cho was kicked out of class due to the complaints.
However, there was no real evidence whether Cho really did filmed his female classmates, or that Cho had filmed his professor (to expose her behavior) which had been misconstrued into filming female classmates. Even if he filmed his female classmates, it might not be sexual. Cho might have thought that the whole class is seeing him being bullied and he might have been filming the whole class to expose their indifference towards him.
After the shooting, Giovanni wasn't surprised that it was Cho. "I knew when it happened that that's probably who it was. I would have been shocked if it wasn't."
Cho had written those words in a whiteboard outside the room of a female classmate, who had exchanged messages earlier:
By a name
I know not how to tell thee who I am
My name, dear saint is hateful to myself
Because it is an enemy to thee
Had I it written, I would tear the word.
Cho probably intended it to be a poem to show his interest. But the girl was creeped out. Then the police filed a restraining order against Cho. Cho then became depressed and said he wanted to "kill himself". He was put into a psychiatric ward for one night.
Emily Hilscher incident
Seung-Hui Cho has chatted with Emily Hilscher, a classmate of his, online. Cho said his name is "Mystery Man" and he didn't want to show his face. In their chat conversation, Cho said that and he wanted to meet Hilscher. Hilscher agreed. A few days later, Cho, near bedtime, stood outside of Hilscher's dorm room and knocked on the door. Cho, wearing sunglasses, said he was the "Mystery Man" and he wanted to come in. However, Hilscher was creeped out. She probably didn't recognize that he was her classmate or that she chatted with him online. She reported the incident and wanted to press charges against Cho.
Hilscher later dropped the charges after Cho explained that it was a "joke". However, Hilscher has gotten a restraining order against Cho. This restraining order against Cho probably angered him.
However, Hilscher herself never really felt safe against Cho. She thought Cho was a stalker and could be a potential rapist. Hilscher's boyfriend brought Hilscher a gun to protect against a possible rape by Cho.
Cho had gotten a heated argument with Emily Hilscher moments before the massacre, and then shot her.
Rejection by escort
Seung-Hui Cho hired an escort a month before his shootings, but he got rejected after he touched her. The escort told that Cho was nervous. His nervousness might be caused by his previous rejection of romantic advances toward his female classmates.
Stalking was legal until the 90's.
The first state to criminalize stalking in the United States was California in 1990 as a result of numerous high-profile stalking cases in California, including the 1982 attempted murder of actress Theresa Saldana, the 1988 massacre by Richard Farley, the 1989 murder of actress Rebecca Schaeffer, and five Orange County stalking murders, also in 1989.
The first anti-stalking laws were written in response to several murderers of famous actresses by stalkers.
Before the 90's, when stalking was legal, stalking didn't seem more prevalent. Stalking is also subjective. Virtually any "unwanted" contact between two persons is considered "stalking." "Stalking" does not need to be sexual. For example, a heated conflict could be considered "stalking" if one party walks away and the other party continues to argue.
Emily Hilscher felt "stalked" which led to a restraining order against Cho. The restraining order against him is probably the reason Cho shot Hilscher in the dorm room. There was a similar case of a restraining leading to a shooting. In the 2012 Azana Spa shootings, the perpetrator Radcliffe Haughton had a restraining order against him. No wonder why both Cho and Haughton became mad. Restraining orders cause violence because they make people verbally defenseless; inciting them to desperately use physical force.
"Restraining orders" only fucking angers one of the parties. If you impose a "restraining order" against someone, you're basically telling him or her to "shut up." "Restraining orders" exacerbate conflicts which both parties had started. "Restraining orders" silence the other party from defending themselves verbally, only compelling them to resort to physical violence. DO YOU FUCKING KNOW HOW MANY MASS SHOOTINGS WERE PERPETRATED BY MEN WITH RESTRAINING ORDERS AGAINST THEM?
