I've been reading DU posts about Harry Reid's letters to Comey... [View all]

... and posts asking why Garland hasn't acted bigtime.. and posts asking why indictments are not raining all over trump and his henchmen/women in Congress.

Why not accept the simple explanation: Fear?

The Powers That Be are afraid that if anything big happens...trump indictments or congressional member indictments, for example... it will start the shooting civil war that is on the near horizon.
The outcome is a foregone conclusion, of course, but the destabilization might kill the economy and send ripples all over the world.
