I don’t see the initial delay for the police to get out of car as troubling. It makes sense that calling the issue into their dispatch to initiate a wider police response would be the 1st reaction.
However, I do find the allowance and lack of warning of passerby’s troubling.
Oh really? It takes two policemen and two Secret Service to operate a radio? One could operate the radio and the other seal off the area? Grabbing for straws.
