Very interesting article however, considering the source it is more of a propaganda piece in my mind. The animation was informative and interesting but didn't sway me one way or the other seeing that rifle rounds, handgun rounds, shotgun rounds are, in most instances, made to be deadly.
Early on in the article they draw a comparison between .223 and a 9mm showing the devastating effects of the .223 with respect to shock wave. They show the "linear path" of the 9mm, and go onto say that is causes, "far less damage". Fair enough, but I am sure the families of the 32 people killed at Virginia Tech in 2007 by combination of 9mm and .22 LR may feel that those calibers were just as devastating.
The go on to dig deeper into this by examining autopsy results of a victim of Sandy Hook and one from the Parkland shooting providing very convincing evidence of the devastating power of rifle gunfire. I am scientist and am always skeptical of data and the way it is presented. When the number of data points is two I ask, "Why?". Were these the most devastating examples? What was the reasoning behind choosing these particular cases? It would have been more informational to provide a cross section of injuries from multiple autopsies for better representation. My guess is that the two they chose would have the greatest impact on proving their point. Scientists do this all the time in data representation. It is irritating but it "drives the the point home", which makes me all the more skeptical.
Finally, if they were to be fair and really wanted to support their argument of the devastating effects of the .223 round on the human body, which I believe to be true, they should have made a comparison. Comparisons are very important in my line of work and provides context to certain arguments. Once again, I go back to Virginia Tech where gunman used a combination of 9mm and .22. They could have looked at autopsy results from victims shot with the 9mm handgun to come full circle with their earlier comparison using the cool graphics showing the "linear path" of the 9mm round and how it causes "less damage". But they didn't do that. I wonder why? Maybe they did but didn't like what they found in the end. I don't know but 32 people still died from their wounds. What I do know is that yes, bullets fired from rifles will mess you up. I am also pretty confident that bullets fired from handguns will also mess you up. I also think it is pretty safe to say that bullets are designed to do that.
