The news that one of Senator Webb's aides has been arrested for (inadvertently?) carrying the Senator's gun into a Senate office building raises a fun question. It seems Sen. Webb gave the aide the gun which the Senator usually carries because the Senator was getting on a plane and couldn't take it on board.
It made me wonder if gun control laws of this sort, when applied to Senators and representatives in any way infringe Art. I, sec. 6, paragraph 1 of the Constitution which states,
The Senators and Representatives shall receive a compensation for their services, to be ascertained by law, and paid out of the treasury of the United States. They shall in all cases, except treason, felony and breach of the peace, be privileged from arrest during their attendance at the session of their respective Houses, and in going to and returning from the same; and for any speech or debate in either House, they shall not be questioned in any other place.
My suspicion that the answer is “no” and that it is proper to apply speed limits, DUI, and other rules of general public safety to Senators and Representatives appears after superficial research to be correct, but not quite for the reason I imagined, at least according to LII's annotated Constitution,
Privilege From Arrest
This clause is practically obsolete. It applies only to arrests in civil suits, which were still common in this country at the time the Constitution was adopted. 376 It does not apply to service of process in either civil 377 or criminal cases. 378 Nor does it apply to arrest in any criminal case. The phrase ''treason, felony or breach of the peace'' is interpreted to withdraw all criminal offenses from the operation of the privilege. 379.
