DHS Memo: Loughner's Mother Worked For The Pima County Board of Supervisors

New details are emerging about Loughner as a law enforcement memo based on information provided by the Department of Homeland Security was obtained by Fox News
Fox is reporting:
The memo also includes information about the suspect's mother, who works for the Pima County Board of Supervisors and notes that Loughner has multiple arrests but no criminal record.
(The Board of Supervisors is in charge of the Sheriff Dept's Budget in most counties)

Several arrests and no criminal record? How does one pull that off? Especially when the whole town knows you're a nut. Unless your mom works for the Board of Supervisors and can pull favor with the Sheriff....
Could Loughner have received special treatment due to his mother's position?
The Sheriff is awful eager to place blame on anyone and everyone as except himself and his dept.

Doth he protest too much?
