Counterintelligence investigations are apparently no longer allowed, except for coups against Trump. But criminal investigations are. It is obvious that the riots and violence are to a great extent planned and coordinated. Barr is pointing out how to get the upper hand.
Step One: Assemble evidence of criminal acts.
Step Two: Get search warrants for all communications, finances, training, organization, political connections, journalistic connections. IOW, actually conduct a competent investigation.
Step Three: Present evidence to Grand Jury. Indict.
Use information gained from the investigation to shut down the funding, command and control, etc., BEFORE it is unleashed on the election and its aftermath.
Why does Barr have to tell US Attorneys to do this?
The US Attorneys prolly know this, some even better than Barr.
Barr did this for the publicity and to get us excited.
I'll get excited when there are indictments of the major players. Are you listening Durham? Until then this is just boring. Words are very cheap.
