"Bosh!  How could they possibly know a thing like that?  Keep quiet, Joseph, while I finish this.  We admit nothing.  Their man is a fake.

If it is necessary to use strong measures and this Smith person gets shot resisting arrest, or something like that, well, it's too bad, but I for one won't mourn very long.  He's been a nuisance all along."
