Special prosecutor Hank Brennan broke his silence on the Karen Read case Monday, warning that the behavior of her most vocal supporters threatens the American legal system as it is known.

“The campaign of intimidation and abuse that has been waged, funded, and promoted in public and on social media is the antithesis of justice. If this type of conduct becomes commonplace, it will threaten the integrity of our judicial system, affecting both victims and criminally accused,” he said in a statement. 

“We cannot condone witness abuse causing participants to worry for their own safety or that of their families.”

One of Read’s chief cheerleaders, Aidan Kearney, a Canton blogger known as Turtleboy, is facing charges of witness intimidation in connection with the case.

“I want to acknowledge the greatest team of attorneys,” he told a crowd after her acquittal on the most serious charges. “Our first one that we found was David Yannetti. We added Alan Jackson and Liza Little. Bob Alessi you know about, all right. It was a fantastic team, but we needed them all to defeat this.”

In a new interview with NBC’s Boston affiliate, he put on a Lexus golf shirt and said his daughter would have told him if she had killed O’Keefe.

“We know Karen as our daughter. Had she done something and struck John O’Keefe, we would have been the first to be notified,” he told the station. “She would have said, ‘Mom and dad, I will take my medicine,’ and it was quite the opposite.”

As for her mother, Janet Read, she thanked her daughter’s supporters and said she intended to pay it forward.

William Read, like his daughter’s defense attorneys, is urging her supporters to go out and vote.

O’Keefe’s family has not responded to requests for comment.
