Mass Shooting PDF Categories and Counts Alphabetical
Mass Shooting PDF Categories and Counts Alphabetical features a Google Chrome simplified view (reader mode) list of mass shooting PDF categories and counts in real time. For users, the “ID” is generally irrelevant, because their generation occurs as new catergories are created for PDFs discovered, received, and/or submitted. Remember, PDFs do not become available to us in a systematic manner; their creation, publication, and distrubution; and our subsequent acquisition, is very fluid at best and very erratic at worst.
Many specific mass shootings appear in two major categories as follows:
—Mass Shooting Documents (MSD) (These are scholarly and other documents that pertain to specific mass shootings.)
—Mass Shooting Records/Reports (MSR/R) (These are the official government records/reports that pertain to specific mass shootings.)
or
—Shooting Documents (SD) (These are scholarly and other documents that pertain to specific shootings, not mass shootings.)
—Shooting Records/Reports (SR/R) (These are official government records/reports that pertain to specific shootings, not mass shootings.)
