This is super relevant nowadays with the news coverage.
The arguments you hear from Anti-gun people are usually more guns = more crime! while the common Pro-gun arguments state, more guns = less crime! Although after looking at the statistics it doesn't seem to have any correlation in either direction.
I like this video. Presentation of raw data and simple extraction of correlation is so much better to me than sensationalism coming from someone with an agenda to push. That said, he makes the thought of actually solving 'poverty, jobs, education' sound far easier than it actually is. In any case, if the people in charge spent half the time they devote to riling up support for non-issues like gun control on the things he mentioned at the end of the video, this country would be in a much better position.
