@blatham,
You are confusing apparently deliberate left wing distortions (or more accurately, selective excerptions) of Trump statements, with the actions of State and Federal legal authorities. Criminal investigations of all of the several groups in the Charleston event were quickly initiated.
This is not at all "irrelevant" to your expressed charge that the President "had excused" such alleged events. Indeed it is the heart of the matter.
The very biased refusal of an Illinois Prosecutor to act on the Grand Jury findings of the Justin Smollett case represents a more obvious miscarriage of judicial procedure than any of the unspecified events to which you are likely referring. Odd that you didn't mention that.
Once again you are confusing actual actions and statements with the vague body of your own preconceptions and beliefs (and those of the many left wing commentators who are the apparent source of your beliefs and prejudices.
If you were to devote just a small portion of the time and effort you give to left wing opinion pieces, instead to inquiries into the facts behind the events and the substance of the issues about which you pontificate so prolifically, your view of the world might become more useful and interesting.
