I don't recall a, "The Federal government must provide logistical support," sub-clause to the Free Speech clause of the First Amendment.
Funny ... I remember DU-folk cheering and chortling when water was cut off to that site in OR being occupied by the property rights protesters. But here DU-folk are upset at taking away water trucks from people protesting a pipeline. [Sarcasm] It's almost as if DU-folks' reactions are based on agreement or disagreement with the causes rather than actual legal rights. [/Sarcasm]
