We're looking at incompetency by the SS, at what level we don't know - was it the person who approved the operational plan? Was it the lack of communication of the SS with local law enforcement? Was it the failure to hold President Trump in the holding area for a longer period of time before he went out onto the stage? Was it the failure to let the SS agents who were on President Trump's detail know that there was a problem? Was it a failure to use drones and test the connectivity in advance? Failure to determine an appropriate perimeter?They're human, just like the people they are sworn to protect. There is no big conspiracy here, just human beings being fallible, just like you and I.
Probably all of the above.
Maybe no conspiracy but definitely incompetence, way beyond infallible man philosophy.
