In regards to 803(8), if the report is by a government agency, and fits under the requirements (what is in rpt/if offered in crim/civil case reqs), then the report is automatically admitted?
Do you need someone to read it into the record? Or is that where 803(5) would come in and if the person doesn't remember the report because they make so many of them and seeing the report wouldn't refresh their memory, then they can read it in. Would there ever be a situation where the entire report can come in?
If the report satisfies 803(8), it comes into evidence. A witness may testify about the contents of the report, just as any witness can testify to what she heard a declarant say. But the report comes in as an exhibit and the jury will be able to see the report in addition to hear the witness talk about it.
If the record is not admissible (whether because it does not satisfy the requirements of 803(8) or because of Confrontation concerns), it does not come into evidence. The person who made the report or observed/tested the things described in the report can testify to what he knows, using the report to refresh his recollection under 803(5). But the jury will not see the report.
