Therein lies the problem doesn't it. Public safety vs privacy.
You end up finding yourself in exactly the same position as the NRA
and I am sure you are both uncomfortable there.
Should a doctor or psychologist be able to put an entry in the NCIC
that would block a gun sale and how do you do that without also
telling everyone else why.
It does open up the question, what else would that information be used
for?
Would employers avoid hiring that person?
Would landlords not rent to them?
Would it affect their credit score?
Would they have problems getting accepted to college?
That would, in effect, be like having "a police record" with all the
ramifications that implies.
... without ever being charged or convicted of a crime, but progressives
see that as ok, as long as the folks they hold near and dear
(themselves) are not held to the same standard...
