Oof, this is a can o' worms.
First off, the school is demented to have created (or announced) such a policy
after people had paid for their trips. To me, that smacks of wanting to corner people and force them into compliance. Add to that the fact that the policy isn't published anywhere (I take it you would not have known about it but for the letter from the orchestra director) and it smells like the school wanting people to commit financially and then spring this on them.
I'd demand to see the entire policy, in writing. I'd demand to know exactly when the policy was passed, where were the public hearings on it, and how exactly was the school intending to communicate about the policy to the chaperones, except via this off-the-cuff letter? This does not necessarily mean I would not comply, but it would leave an exceptionally bitter taste in my mouth about any future trips or calls to chaperone. Personally (and I'm not a parent and it's not my money), I'd sell the ticket on eBay or find some other way to recoup my losses and not go or, if that was impossible, I'd bill the school for my losses and still not go.
But I'm mean and, like I said, it's not my money plus I don't have a child's best interests to worry about.
Fingerprinting is still seen as an intrinsic part of booking a suspect, enough so that, "The gathering of fingerprint evidence from 'free persons' constitutes a sufficiently significant interference with individual expectations of privacy that law enforcement officials are required to demonstrate that they have probable cause, or at least an articulable suspicion, to believe that the person committed a criminal offense and that the fingerprinting will establish or negate the person's connection to the offense. See
Hayes v. Florida, 470 U.S. 811, 813-18 ('85);
Davis v. Mississippi, 394 U.S. 721, 726-28 ('69)." See:
http://www.lectlaw.com/def/f081.htm
While I realize that this is not the police who are going to be gathering the fingerprints, what is the purpose behind the gathering? Would the prints be turned over to the police? And when would this turning over happen? Before or after a crime was committed or alleged to have been committed? Before the trip so as to prevent sex offenders, etc. from going?
For the police, the prints are probably bad potential evidence, what's called the fruits of the poisonous tree, see:
Wong Sun v. United States, 371 U.S. 471, 83 S.Ct. 407, 9 L.E.2d. 441 (1963), and are potentially more damaging than helpful -- surely this is not the school's intention, to possibly hobble any future police investigations?
So the school is probably not doing the police any favors by gathering prints.
Hence this is my bottom line question to the school:
what is the purpose of gathering the prints, and what will happen to the prints once gathered?
- will they be given to the cops before the trip? If so, possible fruit of the poisonous tree situation. Also, this violates the reasonable privacy expectations of the parents.
- will they be given to the cops during or after the trip if there's a problem? Same as above.
- will they just go into a musty file cabinet somewhere in the bowels of the school? If so, why gather them? To just scare people? Nuh-uh, sorry, that's not a good enough reason for violating Constitutional rights.
I'm with your husband. This is definitely something to be more than slightly indignant about. He is and should be outraged.
