I must beg to differ on the statistical validity of this conclusion by MJ. Relative to the total number of homicides each year, mass shootings are extremely rare.

From the PolicyMic story -
.....In 2012, there were either 81 or 88 murdered in mass shootings, depending on your source. Less than 100 no matter, which source, is used. So if we assume high at 100 homicides from mass murder and assume low at 12,000 annual homicides that means that mass murders account for 0.0083 of all homicides, or a fraction of 1%.....
.....There are approximately 4,600 choking deaths every year. That's 46 times the number of mass murder deaths. Children's choking deaths number 1825, or more than 18 times the total number of mass murder deaths......
......According to the Insurance Journal, 200 people were killed by hitting deer with their cars. That's more than double the number of mass murder deaths......
As far as mass shootings increasing, some say otherwise -

2012 was tragically high, but may not indicate a trend. If 2013 is much lower, will that be labelled a downward trend?
