A pile of extreme occurrences does not an argument make.
Because there's insane stuff happening somewhere, to someone, all the time.
With the benefit of digitized news we've enabled lazy trawls to create a pile of "Look at how extreme and crazy ____ is!" to support any viewpoint on any topic.
Anti-gun? Here's some insane gun owners. Pro-gun? Here's some horrific crimes.
That's modern opinionated news in a nutshell -- here's a pile of extreme occurrences, look at how extreme they are, so you should agree that the other side is crazy.
An actual argument involves more annoying to fudge (and admittedly, harder to compile) data like frequency, normalization against population or historical averages, geographic localization, etc.
I've found arguing from questions rather than statements helps. What's the root question? And then what data would answer that question?
