I've just found the Gun Violence Archive on the link in the OP.
This statistic hit me in the eye
There were 27 people killed and 63 injured in shooting incidents on Christmas Day.
Intrigued I went to the Gun Violence Archive (
http://www.gunviolencearchive.org/) and found this mission statement
The Gun Violence Archive is an online archive of gun violence incidents collected from over 1,200 media, government and commercial sources daily in an effort to provide near-real time data about the results of gun violence.
Mission Statement
Gun Violence Archive (GVA) is a not for profit corporation formed in 2013 to provide free online public access to accurate information about gun-related violence in the United States. GVA will collect and check for accuracy, comprehensive information about gun-related violence in the U.S. and then post and disseminate it online, primarily if not exclusively on this website and summary ledgers at
www.facebook.com/gunviolencearchive.
It is hoped that this information will inform and assist those engaged in discussions and activities concerning gun violence, including analysis of proposed regulations or legislation relating to gun safety usage. GVA is not, by design an advocacy group.
The mission of GVA is to document incidents of gun violence and gun crime to provide raw, verified data to those who need to use it in their research, advocacy or writing.
Since this is not an advocacy group it is reasonable to trust the data and with this in mind please note the following statistics

It is interesting to try to draw conclusions from the raw data but that would be a mistake IMO.
For example - there were only 319 mass shooting incidents in 2015 so that's not too bad is it?
Not too bad until we realise that this is equivalent to one for every day over a ten month period.
In that light it is not that good is it?
There were 4,335 home invasion incidents and 1,258 defensive use incidents.
Some of those defensive use incidents may have been in the context of home invasion but it would be necessary to look at each incident to see how many home invasions were successfully defended.
Or how many attempted robberies on the street were avoided.
Still it would be interesting to trawl through the data because it would seem to be verified with references.
