Counter Sniper Ordered Not To Engage! DISOBEYED, THEN Arrested And Lost His Job For Doing So

Trump did not pick and choose his detail, they were assigned by  Kimberly Cheattle the Director of Secret Service.   Cheattle came from the Obama administration.  Her degree is a BA in sociology.  

The claim that she was Senior Director of Global Security at Pepsico - would seem at odds with the current Director, Timothy McCormick, who has had that position since 2014.  His degrees are in Criminal Justice and Law Enforcement.  His bio begins in 1987 when he worked as a special agent in the US Department of Justice.

Meaning - Cheattle did NOT have the experience, the degree, or the expertise as claimed.  Her bio has been modified to alter her experience, and she is incompetent as observed in the selected detail given to protect President Trump.  So, why was she chosen?
