Actually, liberals would never dirty their own hands with a gun--that's why they have bodyguards and servants.
Another ironic twist in this debate is all of the BOR's that mention "The People" all secure individual rights--except the 2nd? Another classic example of liberalthink.
Some leave the job purely to their bodyguards and servants, but some handle them themselves (usually rather badly). In any event, regardless of whether they handle the guns themselves or let someone else do it, those guns exist for their protection and they'll ensure that none of the laws they pass affect them.
