The Confrontation Clause states that
In all criminal prosecutions, the accused shall enjoy the right…to be confronted with the witnesses against him…
But does the Confrontation Clause cover only analytical and conclusory statements, or does it also cover "routine and descriptive and objectively ascertained and reliable facts?" According to a Maryland trial court, it only covers the former. According to the Court of Special Appeals of Maryland in its recent opinion in Green v. State, 2011 WL 2578562 (Md.App. 2011), it also covers the latter.
