“For example, a court could bar Claire’s statement to a police officer that Bob had a gun and was acting like a maniac with either the hearsay rule or the Confrontation Clause.” the police can’t repeat what someone told them in a police report, but if the police had TWEETED what they were told by the witness, THEN SURELY it’s admissible.
