Nothing to laugh about

Did not read the links yet but always question statistics. The definition of a mass shooting that the FBI uses is 5 people shot in one incident. That means a lot of gang activity and idiots are registered as mass shootings. Dr. Lott is indeed the most famous man in the CJ world at this time but I am interested to read these articles later and see what he is using to define mass shooting.
He uses the FBI's definition but i think i saw where it was quoted as 4 or more victims. Throw out the gang related stuff, and the numbers drop exponentially.
