Also we have drones now, so it's easier to have eyes in the sky for such things... but fuck people in the crowd yelling and pointing -- even flagging down event security gave them a 2-3 min warning.
That said DHS and PepsiCo Cheatle need to have their heads roll for this as they blocked man power the event, and they still haven't given security for RFK -- which is very bad optics if they don't want to be seen doing this on purpose. ie They're both evil and stupid.
