A GUIDE TO MASS SHOOTINGS IN AMERICA....

[Whirlaway]

Here is the best single source I could find. It is from Mother Jones, a liberal source so take it for what it is. But it provides a fairly comprehensive historical reference (time line).

Questions it doesn't answer:

How many of these mass shooters are from broken, dysfunctional or single parent households ?

How many of these mass shooters, especially the more recent, were hardcore gamers?

Are shootings being accelerated because of a prolonged economic slump?
