Just read the Wikipedia entry for grand juries - what a ridiculous outdated procedure. Half the states in their wisdom don't even use them anymore.
If this is the quality of witness that was allowed to give uncontested testimony then they need to assemble a new grand jury and fire the DA in charge of the last one.
It seems as if any looney toon citizen can show up and give testimony with nobody to contest anything they say?
I shouldn't judge people by their appearance but this woman looks like she came direct from Central Casting to play 'unstable Midwestern racist middle aged woman'.
