If mental illness is only a factor in the USA with regards to mass shooters, and mental illness occurs worldwide at even higher percentages, then mental illness cannot be a valid factor.

If it was, then you could much easier blame it on water consumption, or the phenomenon of men who wear long pants during certain portions of the year.

It would be inappropriate to group all mental illness into a single group to make those conclusions. There are thousands of forms of mental illness.
