Your argument that stuff in Martin's life prior to being murdered is fair game is not only wrong but down right disrespectful to the victim...

By "fair game" do you mean admissible as evidence.
It is usual for the judge to decide.

You know which one was "the victim" already?
How?

If the trial is conducted fairly then, yeah, that's the way it is supposed to work, however, we have already seen enough misconduct by both the judge and the defense team to see that is not the case here..

You think evidence should be withheld because you think the trial may not be fair?
That would make the trial unfair if it wasn't already!
