I think your point is sound, but I'm not sure this is the best example. Regular shootings are causing a lot more deaths, although I doubt the NSA has any interest in stopping either one (and of course, their official charge doesn't include either one).
I think that sums it up.
> why is it spying on citizens
...is that it's doing that to prevent foreign attacks, not eg. mass shootings.
Furthermore, even if it were doing anything useful with its domestic spying, such as preventing domestic crime, obviously we'd all rather address plain ole' shootings, which take many more lives than mass shootings.
Yeah... foreign terrorism only occurs when foreign entities stand at the border and throw things into our country. LMAO.
On one hand, scoring touchdowns (in this metaphor, preventing domestic crime) isn't their charge.
But on the other, they are also engaged primarily in self-serving funny business instead of hitting home runs (ie, protecting people from foreign aggression and securing the telecommunications systems of the USA).
Such as?
