Ourtsider:  Actually in proactive police work, those "might ofs" you reference account for a great deal.  Yes, I'm an "old man" (if 74 qualifies as "old") and, at some point, my age related issues migh pose a threat to others' safety.  My recently deceased Aunt and Uncle in Oklahoma both voluntarily quit driving because they felt they had reached the point where they posed a danger to others.  The police and DMV have the same responsibility relating to older drivers.  I understand and accept this concern.

AS I suggested, it seems there is a "middle ground" tactic where the police can address an issue of a convicted felon "suspected" of both having and threatening t use, a firearm can be taken into custody, or at least "field interrogated" without a) an armed confrontation or b) completely leaving the scene with the intent of "arresting him later" (which would give him the opportunity to "ditch" any firearm he might possess).  

BTW:  Using the term "Buddy" is condescending.. I'm Gary
