Well, as she has not been found guilty, the trial has not happened yet, you are making some assumptions there. Not knowing the content of the letter makes you assertion that she has shown some restraint a nonsense.
The case has been forwarded for trial... so due process is happening here. Or are you just irate because it is a white granny who is being prosecuted and not an Asian man?
It would also be pertinent that she is a recent convert, God spoke to her and told her what she should do... so she is almost certain to have been, erm, 'extremely certain' in her condemnation of those Satan worshipping Muslims!
