I noticed that as well.
At some point the bikers dropped their weapons and sat down. From what I saw, most weren’t even handcuffed because they were no longer a threat.
Most weren’t gang members but were regular bikers. It was a scheduled Central Texas riders’ meeting. Click the link to the meeting a few posts up and check out the names of the other clubs like the Disciples For Christ MM 1st Annual Jericho Run. It’s not likely CNN will report that.
