Why wasn't the "evidence" presented in open court by the prosecution?
The judge just introduced hearsay.
And you don't have a problem with that?
Not that the defense would ever want to compromise the trial or delay the trial or confuse the trial or subvert the trial. Nah.
Let's think about this for a moment. Either the defense attorney was a seminarian at the same time and same place the abuse was occurring or he wasn't. That's not too difficult to discern.
And if it is true that he did attend the same seminary at the same time when the abuse took place, don't you think that's a pretty salient fact he should have disclosed so as to avoid a mistrial down the line?
