The Capitol Police are 2,300 officers and civilians. They are responsible for 270 acres which is 85.18 officers per acre and they have a $460,000,000.00 budget.
Moreover, my guess is that the force is riven with persons not on the force by INDIVIDUAL MERIT or RESUME but by their various physical handicaps, their gender, their sex, race, their sexual dysphoria, their homosexuality, their nationality, are they trannies and on and on.
If I was worried about the building I worked in being attacked by pissed off Trumpsters, I would want the National Guard outside my window too.
It would be very interesting to see a comparison of the pay of a capitol policeman with the pay of a security person working in a high end museum. Most of the time the job of a castle Capitol policeman seems very similar.
