Law enforcement once again had to intervene when a District 1 resident got into a dispute with Pima County Supervisor Ally Miller, who represents the district.
The most recent incident occurred last week during Miller's town hall at the Oro Valley Library, when Bob Dorson made a comment that led to an argument between the two, according to a Pima County Sheriff's Department report.
Dorson was escorted from Miller's office last month after he showed up to see her office furniture.
At the town hall, Dorson asked the audience if they had an opinion on "a new mine being approved," the report says.
The report didn't identify the mine, but Rosemont Copper has been looking to open a mine in undeveloped land southeast of Tucson.
Miller interrupted him and told him he could only ask direct questions to her.
The two got into an argument before Miller asked him to leave.
A sheriff's deputy intervened, but Dorson was not escorted from the event this time.
Instead, Miller said he could stay as long as he asked questions and did not make any statements.
According to the report, Dorson "did not appear threatening" when the deputy approached him.
Dorson later left at the end of the meeting without incident.
According to a report, there was extra security at the town hall, with two plain clothes Oro Valley Police officers and a sergeant.
However, Miller did not request the extra police officers.
Oro Valley provides the extra police during those type of events, said Lt. Kara Riley, an Oro Valley Police spokeswoman.
