I have written about this topic before, with pretty much the same message, just different details being addressed. The other articles are listed here by date and title, all on this site. I added the search keyword "guns" to all 6 articles.

Since posting this article (or any of the older ones), I have seen nothing in the news (or anywhere else) to induce me to revise these opinions. Not even Wayne LaPierre's recent inflammatory remarks alter my views. He was actually fundamentally correct, in that there surely seemed to be a dearth of armed guards defending the otherwise gun-free zone that was a navy base facility.
The latest incident with Elliot Rodger in California is simply another crazy never institutionalized, and so still able to legally buy guns without any impediments at all. That gets right back to the text highlighted in yellow in the main article above, under "So What Do We Do?"
This is "lawyer/judge nonsense" at its very worst! Until that loophole is closed with a policy that makes good common sense, these horrific incidents will continue, mark my words! Nothing else is going to fix that very fundamental lack.
