Can a consent search be validly qualified by the number of officers allowed to search?

We are unpersuaded that a consent search may be validly qualified by the number of officers allowed to search, and we so hold. Once consent has been obtained from one with authority to give it, any expectation of privacy has been lost. We seriously doubt that the entry of additional officers would further diminish the consenter's expectation of privacy, and, in the instant case, any remaining expectation of privacy was outweighed by the legitimate concern for the safety of a single officer conducting a search of a house known to contain firearms. Cf. United States v. White, 617 F.2d 1131, 1134 (5th Cir.1980) (motion to suppress denied because delay in search and search by agents not named in consent form were not related to the scope of the search).
