In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: threat and non-threat. Threat is a statement that someone will be hurt or harmed, especially if the person does not do something in particular.

Comment: He has admitted to being a murderer...has requested the death penalty. Give it to him...no need to spend money on a trial.
Threat

Comment: So, to summarize, people who voted for Donald Trump and disagreed with you are stupid?
Non-threat

Comment: Good job Mr. Gee. 
Meanwhile a tidbit from the Red Star:
"Mayor John Tory, who said he was “deeply concerned” about the event, said his office will ask the library to review its room-booking policies going forward.
While the mayor had asked the library to consider cancelling the event, he was told they’d received legal advice that they couldn’t deny the booking." 

No wonder it's getting harder to preserve our hard-won Freedom of Speech.
It's one thing to have squads of Marx's Little Helpers on campus twittering themselves thumbless with carbon-free rage every time they hear that someone might be about to say something they don't like - those stories are so stupid they're funny. 
But when the Mayor of Toronto doesn't appear to understand what free speech is that is just unacceptable. 
Tory and similarly civics-deficient public officials need some remedial learning.
Maybe they can book a room at their local library.

Non-threat
