A better category would be “Gun control” or “Public Safety.”

While the real issue here is gun control and education, since those are absent, it seems to be time to sacrifice a little privacy in exchange for safety. Perhaps municipalities could take advantage of technology and issue their residents cards, stickers, dog tags, or key fobs with barcodes that are linked to identification. These would have to be scanned at the gated entrance to parks, libraries, schools, parking lots, and other public facilities, allowing only those with prior city authorization to enter.

no sacrificing privacy. No one has a right to privacy in public. Cameras are a good idea.

I could not possibly agree more with you! Public Safety is worth whatever it takes.
What’s that judge’s statement, cited in the 1919 Harvard Law Review, often misquoted or misattributed? “Your right to swing your arms ends just where the other man’s nose begins.” How might this translate to gun use?
