ok looking at their site again.

"We do not consider the motive of the shooter, or whether he or she shot up a school, workplace or street corner. Our mission is to record all incidents of mass gun violence."
but this includes gang violence. i hope you agree it doesn't matter what gun laws or bans you put into place, these events will not stop. I don't think they will decrease either as they will still be able to get guns. Please don't say they will not because i will feel trying to discuss this further with you will be pointless and/or give me a headache.
"We include the shooter's death because suicide matters and means matter. Ignoring the shooter's death is not logically consistent with research that tracks the death toll of firearm suicides in our society."
This doesn't seem logical. Yea, the shooters life was ended, even if by suicide, but why should it count in the stats? Nor should it be counted if the cops shot the shooter. though by their on definition, it shouldn't count because the cop would be a different person. firearm suicide shouldn't be included. if suicide was their only intention, there are other ways. It may or may not be relevant to the above quote, but i'll add here that murder suicide of a family should not be counted either. Not sure if they do count that, but they probably do. Why should it not be counted? because it was likely done in private and not having a gun would probably not have stopped it from happening.
As for all of the news stories, one thing seems clear when clicking on them. they are involving a lot of criminal based activity. one of them were on federal agents trying to arrest a fugitive at a motel. why should these things be listed and given the same weight? laws nor bans will have any noticeable effect on them. they do point out we, though we ar not alone, do have a serious "violence" problem. it's not just guns. these people would be violent no matter what tools they had with out looking into why they are violent. With out working to find and fix the root cause, it isn't going to matter what you do.
