U.S. v. Webster

In prosecution on drug and firearm charges, Dist. Ct. erred in admitting evidence of forensic laboratory reports that confirmed existence of drugs at crime scene, where said reports were admitted into evidence without testimony of analyst who prepared said reports. However, error was harmless where defendant never contested at trial that substances found at crime scene were in fact drugs. Moreover, Dist. Ct. did not err in admitting taped conversation of defendant that was made in caged backseat of squad car, since defendant did not have objective reasonable expectation of privacy with respect to said conversation.
