He appeared in federal court in Boston on Wednesday afternoon and is being held pending a detention and probable cause hearing scheduled for Monday, according to ABC Boston affiliate WCVB-TV.”Simply put, words matter, and today’s arrest of Matthew Haviland should serve as a warning to others who think they can use the internet to terrorize people. Don’t do it,” Joseph Bonavolonta, special agent in charge of the FBI Boston Division, said in a statement Wednesday. “Everyone has the right to express their opinion, but when you threaten, harass, intimidate, and put others in fear for their lives, it’s a federal crime,” he added.Copyright © 2019, ABC Radio.
