I'vebeenduped, while Angel1495 had a good point about posting appropriate statutes, his specific citation did not support his argument. It was specific to handguns.
Meanwhile, while the law could be interpreted to say that Grisham was carrying in a manner that might cause panic, and while you have reaffirmed that the law could be construed to mean that, unless things have changed the local prosecutor has not charged him with unlawful carry. That tells me that prosecutor does not want to make that argument.
If any charges have been added, since they reduced the original ones to interfering with a LEO in performance of his duties, anybody is free to update the current charges.
But it seems to me that prosecutors only reduce charges like that when they suspect the court case isn't so good, and they hope the defendant will accept the lesser misdemeanor in a plea.
