Let review this farce without all the noise, blame shifting and screaming being generated in the old Media today
Here is the question that must be answered.
You are a supposed highly trained, high paid security professional working for the state of the class US Secret Service. SOP is to lock down any roofs with ladder access within sniper range of a high risk target. You are assigned to guard the highest at risk target in the world.
However, magically, yesterday you total forgot to secure a roof top 150 yards from the opposition party’s political candidate. A roof top that also had line of site to the egress path the candidate would be rushed down in case of an emergency.
Magically this “random nut” penetrated your security zone, while carrying a rifle, decided to crawl up onto that roof and gets off 8 shots at said high value target before you even responded.
If random people out here can see the obvious flaws in the security set up, why did the highly paid, highly trained people running the SS miss all of them?
You nailed it. And the question is, were the flaws “missed” or was this part of the plan?
