58 people were killed in mass shootings in 2017 (considered the deadliest year for mass shootings in at least a decade).
From 2005–2014, there were an average of 3,536 fatal unintentional drownings (non-boating related) annually in the United States — about ten deaths per day. An additional 332 people died each year from drowning in boating-related incidents.
One out of five of those who drowned were under 14. That’s about 707 children.
I think you really should be advocating for banning swimming pools.
