If I had a lunatic running around in my neighborhood killing people I would want to be armed.
The problem the democrats have selling the gun controls laws they are trying pass right now is they have not done a very good convincing people they will have any impact. Like your example here people look at Sandy Hook and even though they are frightened and angry the dots don’t connect. If you cannot get a law through the democratically controlled senate that polls at 90% what are the chances you may want to look at your sales tactic and stop trying to hijack a tragedy to sell it.
