There seems to be a discussion that the gunfire took place adjacent to the parade but not in it, with belligerents fleeing through the crowd. Decoy Voice posted this video which suggests that one suspect was apprehended with an AR pattern weapon of some kind. Can't tell from the picture if it's a rifle or pistol, but the buttstock looks like it could be a rifle of some sort.
