&gt; Namely, law abiding citizens should be able to conceal-carry weapons. Although it couldn&#x27;t stop all kinds of terrorist attacks, it could very well put a stop to most mass shootings.<p>Here we go again...<p>When I read this, in my head, this analogy comes to mind: &quot;We could stop bombings by allowing all citizens to carry concealed bombs [to use in self-defense].&quot;<p>Now obviously that is an absurd analogy, but it mirrors a lot of what you&#x27;re suggesting: fight a dangerous weapon with another dangerous weapon, potentially put bystanders in harm&#x27;s way, make it even harder to track&#x2F;identify the good from bad, make it easier to obtain weapons.<p>The US has more mass killings than any other western nation, yet they also have concealed carry, clearly something isn&#x27;t working here. Is the solution really &quot;more guns, more guns?&quot;
