See the article Kim posted at #23 which contains the following:
In court documents filed several months ago, prosecutors attached a police report stating that on Feb. 6 a police detective at the impound lot told other officers that "search dogs had alerted on a storage area located on the exterior of the motor home near the main entrance on the passenger side."
I would think the prosecution will be giving that report to the jury. The witness yesterday wouldn't have been able to testify to a report he had no hand in writing, I would think. The defense speaks Clintonese, as defense attorneys are wont to do.
