If "assault-style weapons" are banned either in DC or on a national scale, all guards of government bulidings and officials must abide by them without exepmtion.
If assault-style guns are banned and high-capacity magazines are banned, then the secret service and capitol police cannot carry and use them.
If all guns are banned and mandatory buyback or confiscation is made into law, then all security surrounding government officials must be unarmed
This is be one nation under God where ALL men are created EQUAL
...and NO MAN OR WOMAN has the right to more security amd safety than anybody else
