Casting a shadow of doubt where none exist is reaching beyond the duties of competent legal counsel, and criminal. IMO.

Again, this kind of begs the question. If no shadow of doubt exists, then it is impossible to cast this shadow. If a doubt exists in the minds of those the lawyer brought it up to, then it clearly exists. It is the lawyer's job to bring up doubts in the minds of the jurors that they may previously have not thought of.

This sounds good, but it inherently false. That's why witnesses are attacked when their testimony can't be refuted. Some lawyers seem to thing their job is the divorce common sense from society. When they succeed, they subvert the judicial system.
