A threatening tweet can be considered a crime
Tweeting is protected under the First Amendment freedom of speech rights, but there are exceptions, especially when security is at stake.
An Alabama man is awaiting sentencing next month after pleading guilty to threatening to kill President Obama in a series of messages he sent out over the social networking site Twitter that referenced an anti-government militia group. Jarvis Britton wasn’t found to have any connections to the militia group and he apologized for “acting stupid” in sending out the tweets, but he now faces up to five years in prison.
