The Supremes have ruled on this before. No duty to protect any one individual. DemocRATS will never acknowledge this as they try and disarm Americans while they put more felons on the streets who have more rights than law abiding Americans.
The government gets to have both.
Unless you overthrow it.
Of course they can.
The government has lots of guns at every level, and has no compunction against using them at all. They can make whatever silly rules they want, and there isn't a damned thing you can do about it until you are willing to be every bit as violent as the government is willing to be at the drop of a hat.
I'm actually surprised that so many people on this forum didn't already know that the cops don't have a duty to protect citizens. The law on this is very firmly settled and has been for decades.
