You can see my comment below for some facts about the Netherlands. They do, literally, have a militarized police (the gendarmerie) which has civilian duties while operating under the defense ministry (and having military duties as well). They operate at airports, do border control, protect state assets (especially in capitol), do crowd control at major events, contain riots etc. You will see them if you go and even try to look.

Their normal police is very similar to America's in number and capability. They may be trained better, which seems like an argument for better training.

I have the opposite hypothesis: I think more police, even from the NG, will help. I think if our society is more criminal, for whatever reasons, it should be policed more. I do not see any good arguments for how having a few hundred NG deployed will strip me of any important liberty, and I think it is much better than tech solutions in that regard.

We now have a test case, and we can come back and see.
