In 2015 they have been closer to one a day. Prior to 2015 they have averaged less (I've seen different numbers,)

Mass shootings on a daily basis? I haven't GOOGLEd the statistics, but that seems a little exaggerated to me. Of course, I guess it all depends on how you define "mass shootings". I surmise that in a country as big as the US that there is probably a shooting somewhere in the country on a daily basis.
