I would as soon as possible speak to an attorney regarding this issue. Things might be different in different jurisdictions, but I would want to find out from an attorney if your county/state has laws regarding the necessity for a parent or other adult representative being present when a juvenile is being questioned about a possible criminal act. Yes, juveniles can be questioned by police when that juvenile is not the subject of an investigation. But, in your case the focus of the police was directly upon your daughter, and an adult (parent or other) should have been present before police questioned her. I’d be mighty P!SSED if that were my child.
a parent is negligent if they do not repeat over and over, never under any circumstances speak to a police office about anything.
I’d talk to an attorney. I’d also talk with the school & school board, and tell them I didn’t want my daughter talking to cops EVER without an attorney present. I’d also teach my daughter to refuse to talk to the police without an attorney.
A few sentences exchanged in public is OK, but the moment it looks like they have ANY interest in you, shut up. Nothing you say will help, and much can get you in trouble.
