Ben has done several deep dives into various aspects of how the public processes mass shootings, and recent events moved us to bring this topic out now. As political talking heads and newsmakers cherry-pick and sound off about their own causative theories and narratives, what will and won't work to curb these horrific events, we thought we'd take a look into what we do know, and don't know, about the profile of an "average" mass shooter. Data on mass shootings, and other gun violence, is lacking for a reason, and that's soon to change, which will hopefully allow a more rigorous, public-health approach to this subject.
