I think alot of people are equating these grand juries with trials

which they aren't

bottom line

the POTUS can basically do whatever the fok he wants

as we've seen with immigration, ISIS, Obamacare, etc...

they are choosing to do nothing.

Laurence O'Donnell point blank pointed out that McCulloch's office presented an outdated statute to define justified lethal force

the statute that allowed for lethal force if a suspect is fleeing

was struck down by the Supreme Court

i.e., the DA's office presented false evidence to the grand jury

which should be enough to assign an outside prosecutor IMO
