First, I'm going to heavily qualify this statement. Like, a lot. I have never served in any military capacity and I'm repeating something a member of the Canadian military told me, which could easily be wrong for 20 reasons.
National Guardsman are similar to our "reservists" and are not paid when inactive. If additional troops who were already trained but not active, we're then activated, that would account for additional costs.
So yeah, massive grain of salt but you asked and someone gave me a reasonable answer that seemed to fit. I have done no fact checking, though.
I'm late to this party but I always like to chip in on Luigi threads:
It would seem to me, that Luigi is a troubled young rich kid who wrote some critical, if meandering, things about his frustrations with US Healthcare, got accused by a McDonalds employee who was financially incentivized to see a suspect, had evidence planted by some cops hoping to catch this rising folk hero before anyone else got any ideas, and then got railroaded by the most corrupt DOJ since the Gilded Age.
