This appears from afar to be a massive failure by the Secret Service. I have a family friend that worked on the VP detail years ago during the Clinton admin. I may reach out and get his take on it, but to me, it looks like they dropped the ball. Bad.
Yeah I coached 2 kids, both dads were secret service, travel detail guys(they’d travel out ahead of time and check routes, plan details and such) retired tho. I may try to reach out and see if they’ve got a thought on this as well.
