Hell, why stop on the streets. Do it at every entrance to the Capitol building, and all of the House/Senate office buildings. Hell, CBP/BP claims that the protections guaranteed under the Bill of Rights are "relaxed" in relation to border security issues, so it shouldn't matter to them that this method would unduly impact the Right to Petition for the Redress of Grievances.
