Well... To me, this reads as: 'Do Your Job and Enforce Existing Laws'... as opposed to trying to use an executive order to create NEW laws. [Shrug]
Ever wonder how (truly) mentally unstable shooters fall through the cracks in the system? Many patients who could become a danger to themselves, or others are many times NOT reported to the Database due to the gray area of being a HIPPA violation. As an Executive Order would supersede HIPPA, it could ease the fear of HIPPA Violation suites.
But yes... this part could very easily turn into a '1984' 'Big Brother Is Watching' situation... Anyone diagnosed with PTSD, ever been on Depression meds, etc., could theoretically be put on a Red Flag list.
A slippery slope, unless everyone reported to the list is given a fair and impartial hearing BEFORE being put on the list.
