That infographic is informative to a point. The Sandy Hook massacre involved a guy who killed his mother to take her legally acquired guns, which were then used to maximum effect in the elementary school.

So, even in that instance, you had a case where someone who legally owned guns ostensibly for their own protection was killed in order to perpetrate an even greater killing spree. What should have been a death knell for the whole nonsensical meme that a good guy with a gun beats a bad guy with a gun gets ignored even though the proximate cause for that massacre was the guy’s ability to take the guns his mother had legally purchased. Those guns made everyone less safe - not more so.
