The courts have ruled against the tribe in everyone of those filings to date none have been successful.  Tribal officials were invited to over 44 meetings when the pipe line was in the planning stages.  They did not attend any of the meetings.  The tribe lost control of this protest long ago.  Tribal leaders have asked the non Standing Rock tribal members to leave go home.  It is those from out of state that frankly do not give a d(*& about the tribe that are the cause of all the violence and criminal activity.  And there are NO water cannons in the entire state of North Dakota.  It was one fire truck with one hose there to put out the fires the protesters were starting.   And yes the entire area was sprayed with the hose to make starting any more fires difficult.  Did people get wet yes they did.  Were they going to die from it no, they simply had to return to their camp and change clothing.
