I don't think that's correct.
The children killed in school shootings are absolutely murdered by guns... by bullets shredding their bodies at high velocity. They're not being punched or choked to death by people, they're being shot... in their classrooms... with guns.
Without guns, the murderers wouldn't be able to kill nearly as many children in these school shootings.
Politicians don't want to ban guns... they love receiving money from the NRA. It's parents and citizens who want common sense gun regulations. The majority of Americans polled by the Pew Research Center want more gun regulations. That's not politicians, those are your fellow American citizens.
I don't know about mass shootings per capita, but by school shootings the USA has a very serious problem:
19 Countries with the Most School Shootings (total incidents Jan 2009-May 2018 - CNN):
United States — 288
Mexico — 8
South Africa — 6
Nigeria & Pakistan — 4
Afghanistan — 3
Brazil, Canada, France — 2
Azerbaijan, China, Estonia, Germany, Greece, Hungary, Kenya, Russia, & Turkey — 1
