McGurk briefly spoke about the incident in court this morning.
"The whole thing was blown out of proportion," he said.
McGurk asked the judge for a court-appointed lawyer. He is charged with simple assault, resisting arrest and driving after suspension in connection with the I-93 incident.
He was also prosecuted by Salem police on a theft charge for stealing the Grand Am. Prosecutor Jason Grosky agreed with the $150,000 cash bail set by Coughlin and asked that McGurk be barred from having contact with the vehicle's owner.
After the arraignment, New Hampshire State Police Lt. Christopher Wagner said they were pleased with the high bail set by the judge.
He said Powers is recovering from his injuries, which were minor, and expects to return to the state police force later this week.
"He is doing well," Wagner said. "He is taking a couple of days off to recuperate."
Wagner also spoke of the show of support in court from Powers' comrades.
"We stand strong for one another," he said.
