A recent article posits that when using videotaped testimony to cross-examine a live witness, the videotaped testimony is more compelling. Richard Rollo drafted an article for Delaware Lawyer discussing the use of videotaped depositions or testimony, and says "For some reason, the videotaped testimony seems more believable than the testimony given live."
Rollo’s article is not yet available, so it is unclear how he reached that conclusion. Nevertheless, it is certainly an interesting concept. If proven correct, this could signal a shift in how depositions and interviews are conducted. More and more police departments are switching to videotaped interviews, likely in response to defense attorney challenges about coercive interrogation techniques.
