Gate agents ask everyone to sit and avoid gate area…no one moved…

About to board a full flight from ATL to LAX. TSA is checking everyone’s IDs for some reason at the gate. The gate lice were hovering. They’ve asked everyone to move and sit down. Not one of the 20ish people moved. Asking again, everyone is staring at the gate agent with blank stares and more people just stood up and walked over towards the gate area. No boarding announcement yet, either. Any bets on the level of shit show this will become? I’m going with about a 7.
