A mind blowing stat to me is that there are 2,200+ Capitol police. 22 fucking hundred officers primarily to protect a couple of buildings (yes, I know they have to provide security for congress members too, but they were in the buildings at the time) and they can't even do that. That's completely separate from the 4,000 regular DC police too.
I guess it's not surprising that a ridiculously bloated force whose members stand around scratching their dicks all the time can't effectively respond to an actual emergency.
It's something Americans often don't comprehend, is that while you whine about socialist gubments, you probably have the most inherently wasteful public sector in the developed world because of your security state. You have so many completely useless jobs in policing, military, intelligence, prisons, courts etc. on top of the usual bureaucratic bloat you find in other countries too.
