Kevin Blacker’s self-proclaimed “act of civil disobedience” in 2020 led to a guilty verdict Friday in his misdemeanor vandalism case.

A jury of six in New London Superior Court found the Noank resident guilty of second-degree criminal mischief for painting three signs pink in New London in 2020. He received no prison time or any fines but had already paid $586 in restitution.

Blacker is a longtime vocal critic of the Connecticut Port Authority, the agency that oversaw the redevelopment of State Pier into a staging area for the offshore wind industry.

The state-owned signs Blacker painted were directional signs related to State Pier. He had used the arrest to gain attention for his cause. He similarly painted pink stripes on doors at the state Capitol last year and got arrested for that act. Blacker paid restitution and was not prosecuted in the Hartford case.

New London Superior Court Judge Jassette Ann-Marie Henry on Friday, after being provided information that Blacker had paid the full $586 in restitution to the state Department of Transportation, sentenced Blacker to an unconditional discharge and ordered him to pay a $15 court fee.

Blacker had represented himself in a two-day trial in which Assistant State’s Attorney Alexandra Aksterowicz offered evidence, including audio recordings, to prove Blacker had freely admitted his crimes and in fact had said he expected to be arrested.

In her closing arguments, which lasted about five minutes, Aksterowicz told jurors that the case boiled down to whether Blacker intentionally damaged someone else’s property and whether the damage exceeded $250.

Blacker, in his closing arguments, told jurors “a reasonable person in my situation viewing the circumstances from my point of view would have believed they just didn’t have a right, they had a duty to do what they did because a reasonable person fears a dishonest government and the bystander effect.”

Aksterowicz said Blacker’s claims that he was justified because of a cause “doesn’t excuse the fact a crime was committed.”

After the trial, Blacker said he had no regrets but had been worried about the possibility of prison time and a large fine.

“I’m feeling extremely relieved. I had no expectations whatsoever, no idea what to expect for a verdict or a punishment,” Blacker said.
