There should be an investigation into Sheriff Dupnik. Was Loughner receiving special treatment by Dupnik because his mother worked for the Board of Supervisors?
And is Loughner’s mom Sheriff Dupnik’s boss in some fashion? Does she have any influence into his compensation and departmental budget?
This needs to be investigated. You’re spot on in your reasoning. Not that there is anything there, but the possibility exists and should be looked in to.
