Who gives a flip about a 'frighten judge' which is all in her mind anyway. It is not reality but what is reality is Zimmerman's life is on the line and he's the one being threatened and has been since the beginning! If she can't stand the heat, she needs to do the right thing and step down so Zimmerman can have a 'fair trial'. She's an *ss walking out like that - unprofessional comes to mind. She cannot think past her fear or bias - unqualified to be a judge comes to mind, also.
Being a judge is all about justice.
It's glaringly obvious you've never studied law.
