The teenager was downloading publicly available records on a Freedom-Of-Information portal. Why law enforcement is involved, or why this is even remotely a criminal act, completely baffles me.
Sometimes you get Freedom of Information Act information because you got an individual's consent to release information that would otherwise not be released (e.g. something about your spouse/family member that consented to the information not being redacted).
Perhaps the same portal handled Privacy Act requests where people requested their own information that the government holds.
