Not people who "need help with their finances."  Individuals on SS Disability for mental-illness whose mental-illness was so severe that the SS Department took the legal step to require that a "money manager" control their finances.  It only addressed those with that severe "mental illness" as the cause for requiring the management of finances when limiting their eligibility to purchase a firearm.  We all, at least I think we all, feel it would be advisible for the seriously mentally ill to NOT have firearms.  These folks are defined by the SS dept. as having severe mental illness.  The "due process" element was the process of their being determined to require a money manager to receive SS benefits. 

You can take your shots at President Obama on this, but at least be accurate.  The Order addressed ONLY a small number of individuals categorized as severely mentally ill.  Obviously, it wouldn't keep guns out of the hands of all mentally ill individuals, but it would have helped a bit.
