Why the dramatic spike in mass shootings lately?

That’s the problem with 24-hour news channels – there’s so much airtime they have to find some way to fill.

As a former newspaper reporter I take exception. There are plenty of credible media institutions out there, still; they make mistakes but don’t lie on purpose.

Don’t y’all know that it’s all being set up by Obama so he can get guns banned, and our front doors broken down without a warrant and our houses searched for them?

(Yes, there are people who really do believe this.)

Or right-wing fear mongering is pushing some borderline cases over the edge.

It used to only be the voices in people’s heads that drove them nuts. Now there are actual voices on the radio, TV, and internet sites whispering in their ear.

In Micronesia there was a sudden spike in suicides as well http://marginalrevolution.com/marginalrevolution/2003/10/suicide_and_mul.html

“As suicide has gained familiarity among youth, the act itself has become increasingly more acceptable or even expected. Suicides appear to acquire a sort of contagious power. One suicide might serve as the model for successive suicides among friends of the first victim.”

My WAG is that whoever is making this correlation is doing so by cherry picking the time frame. Sort of like AGW deniers IMHO. If you look at these things over longer periods of time I think it evens out. You are going to have spikes and lulls on any random event like this, and the spikes probably represent a bit of copy cat behavior…or, simply probability coming into play where you have clusters of events that don’t really signify anything specific. Like tossing a coin in the air a million times…at some point you are going to get clusters of a bunch of heads (or tails) in a row.

Could it also just be a simple issue of population growth? A constant percentage of spree killers in a growing population means you get a rising rate of spree killings.
