How Thomas Matthew Crooks got onto the roof of the warehouse for a manufacturing company called AGR International is still unclear. It’s just one of the things that don’t make sense about the assassination attempt on Donald Trump. Stranger still, the Secret Service had identified the building as a potential vulnerability before the rally even began, two unnamed sources told NBC News. However, the Secret Service instead left the securing of that building, along with several others, to local law enforcement.
Kimberly Cheatle, the Secret Service director, said that her agency “was responsible for the inner perimeter” and “sought assistance from our local counterparts for the outer perimeter.” Nonetheless, many experts, including one of the unnamed NBC News sources — allegedly a former high-ranking Secret Service agent — believe the Secret Service should still have been responsible for securing the building Crooks used. “Just because it is outside of the perimeter, it doesn’t take it out of play for a vulnerability, and you’ve got to mitigate it in some fashion,” the source said.
