Whenever I read these lame attempts of yours to play Perry Mason I just have to laugh.
Impeaching Bergman's statement will be child's play...in fact, the prosecution wanted to question Bergman directly but their request was turned down by the judge who said procedural rules for probable cause hearings would not allow it.
Likewise to you. At least I cite to what was said, whereas you and the prosecution resort to strawmen and dishonest argument to support your accusations.
Any further impeachment of Bergman depends on the state charging him with a crime. I predict that no charge will be filed against Bergman, so whatever points the state scored served their purpose - he still stands accused as far as the legal system is concerned.
