Carl, here is the case I was talking about on securing a "suspect's" fingerprints, warrant wise that is:
p.816:
We also do not abandon the suggestion in Davis and Dunaway that, under circumscribed procedures, the Fourth Amendment might permit the judiciary to authorize the seizure of a person on less than probable cause and his removal to the police station for the purpose of fingerprinting. We do not, of course, have such a case before us. [Footnote 3] We do note, however, that some States, in reliance on the suggestion in Davis, have enacted procedures for judicially authorized seizures for the purpose of fingerprinting. The state courts are not in accord on the validity of these efforts to insulate investigative seizures from Fourth Amendment invalidation. Compare People v. Madson, 638 P.2d 18, 31-32 (Colo.1981), with State v. Evans, 215 Neb. 433, 438-439, 338 N.W.2d 788, 792-793 (1983), and In re an Investigation into Death of Abe A., 56 N.Y.2d 288, 295-296, 437 N.E.2d 265, 269 (1982).
