I think the difference is people spend relatively little time on the perpetrator having some propensity to have issues (as will happen to some people when you have 7 billions-strong-bell-curve of them) and a lot of time on what could have triggered/exacerbated their issue (which could be a lot of things that don't cause issues in most people). For example, video games, pot, guns, etc. which don't cause issues in most users but seem related to issues in some users. This leads to an over focus on banning the thing most people use without issue rather than recognizing the statistics of 'out of 7 billions people some will have issues'.
