Police demand that witnesses rehearse testimony

IN THE YELLOW HOUSE CASE A SUBPOENA SENT OUT FOR APPEARANCE AT TRIAL INCLUDED A HANDWRITTEN Note by the officers, (added after the Judge signed the subpoena) with a date and time for witnesses to appear at the police station to practice and go over trial testimony.

The witness is expected to have a clear recollection of such events, a copy of which the advocate will have in front of him/her (i.e., in a witness statement document). The reason being that it is the oral evidence given in court that is the evidence, and not the document.
