40,000+ people overloaded the two towers present. At&t has its Firstnet service that is specifically for first responders and LEO of any stripes. Firstnet gives priority realtime access to the network for any authorized user on dedicated frequency bands so normal users don’t overload it. Why SS and the local LEO were not using Firstnet is another question that needs to be answered. Iridium satphone also has a dedicated LEO and military priority service. Here again you only need a dozen or so phones hand them out to watch commanders. Then there is the military MOUS handheld comms that is priority ,encrypted and redundant with zero civilian access or interference. A couple of singars and the modems to each watch center would link them all tougher using military grade comms. Fail,fail and more fail.
This is not the Secret Service’s first rodeo.
These are ridiculously routine issues that must have been addressed thousands of times before.
They are doing the old street scam—shell game—lying.
