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: Fire the lying, crooked cops. 

If the shop didn't want his business, they wouldn't have sold him the muffin.

Also release and exonerate everyone the crooks have ever accused of a crime. The lie about muffins for no reason, they will obviously lie about everything else too.
Threat

Comment: Bah. You must be too young to actually remember what did happen. Google Reagan and SDI. The thought of SDI had the Russian high command crapping their diapers. 

You have totally underestimated Reagan. Not saying that he was a MENSA candidate but he certainly was no fool
Non-threat

Comment: Shoot my dog on my property and you will be shot right back. Other people don't value your life as much as you do. Keep your gun away from my yard and my dog and this won't happen.
