Anyone who’s ever been civically active in a small town, can tell you that Borough Council meetings are often flypaper for the drunk, crazy, or attention starved. Usually switching off their mic is enough to get them to go away and/or sober up. Security can be an issue for Borough meetings, but generally the presence of a few officers, who would be there anyway, is generally regarded by most small Boroughs as sufficient for keeping order.
That is, of course, unless you’re a small borough in New Jersey, in which case nothing less than H&K submachine guns will suffice. I have to agree with Tam this won’t end well.
