“Shining a laser into the eyes of officers has occurred at a number of protests around the country and is very dangerous to the officers,” the charges said. “Multiple officers in the United States have suffered significant damage to their vision as a result of being hit in the eyes with such a laser.”

The officer was wearing special safety glasses and was not injured. The officer identified Mussa McCaskill as the person who allegedly turned a laser on and off a few times.

A laser pointer was found on Mussa McCaskill, who admitted to her actions, the charges said.

More than 600 people were arrested after protesters blocked the interstate late Wednesday and early Thursday.
