on a certain gun-control related video

[Ibrahim90]

so, I've been browsing the subs when I saw this video, from one Bryantulsa:

in his video with these studies, which are interesting, and for all I know, correct (being unable to access many, if not most, sources, it's hard to ascertain the quality of the papers, but I've confirmed that they are all actual papers/sources). However, I do have a few things that I feel he left out:

1-how does this address/solve/minimze the issues regarding mass murder in schools, and why they occur? that is to say, can there be a proper set of gun control laws that can somehow filter these people out?
2-where are the comparisons between countries with lax gun-control and each other? and where are the explanations and details regarding the outliers? he makes a passing reference, but no new research is present. what of Switzerland? what roles does culture play?
3-finally, as I cannot access the paper, I can't tell if he's confusing Gun violence with overall violence--especially when in the last part, he discusses the efficacy of gun control laws.


I'd like to know your thoughts.
