Concord Police Lieutenant Sean Ford says the vandalism is evidence of the times.

“In today’s atmosphere, I think we all can agree that this is not a tolerable message to put on any surface. The message itself is extremely concerning to this police department and I’m sure in the community at large,” Ford said.

New Hampshire Democratic Party Chairman Ray Buckley agrees that the act was unacceptable.

“Vandalism is unacceptable, it’s inexcusable and it’s wrong. The New Hampshire Democratic Party wholly condemns this criminal action and hopes the perpetrator is held accountable. There is no place for that in our politics,” Buckley said.
