So this is what the law firms bent the knee to do

See § 2 of the latest play-acting bumptious dictum from the White House:

Legal Defense of Law Enforcement Officers.  The Attorney General shall take all appropriate action to create a mechanism to provide legal resources and indemnification to law enforcement officers who unjustly incur expenses and liabilities for actions taken during the performance of their official duties to enforce the law.  This mechanism shall include the use of private-sector pro bono assistance for such law enforcement officers.

So now we know what Paul Weiss, Wilkie, Skadden, at al. committed to spend $ 100 million--defending cops who shoot people, even where their employers already defend them. Trump does not want to provide counsel to people who usually do not get it; he wants to save police departments from the cost of even having to defend these guys. Note the system it creates: Cops pay nothing (protected either by QI or indemnification); cities pay no damages (too hard to prove a Monell claim); cities and departments do not pay defense (or insurance) costs, now borne by these law firms.

Congratulations, Quislings. I am sure this is what you meant by a shared commitment to "ensuring the fairness of the justice system."
