Yep, the show manager should pick up that someone who repeatedly has a table for his 'collection' is funny business.
That's how shows get closed as attractive nuisances.
Penny-wise and pound-foolish. The gun show promoter's greed in collecting the table fees from Copeland led to the show being kicked out of it's usual venue. Let's hope that it serves as a lesson to other gun show promoters who sell tables to serial "private collectors."
Violence is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and valorous feeling which believes that nothing is worth violence is much worse. Those who have nothing for which they are willing to fight; nothing they care about more than their own personal safety; are miserable creatures who have no chance of being free, unless made and kept so by the exertions of those better than themselves.
