If this is true, and if the bus was officially owned by the campaign and if this was coordinated in any way by the campaign, this is a federal crime under Title 18 of the US Election Code regarding interfering by means of intimidation with political campaigns. It may even go one step further if it is found that Paul himself knew in any way about this as it would be both coordination with an outside group as well the fact he is a congressman so it would be a double whammy as lawmakers are also prohibited by law from interfering with a campaign.
I partiallly disagree. The question isn't whether it's a crime, rather whether the criminals were official paulistinians. It's a crime.
Will the Holder Justice Dept investigate?
Doubt it, they haven't in the past.
Should have added for the benefit of the paulies, if you wonder if I’m making a moral equivalence between paulestinian thugs and new black panther party thugs, absolutely, I am.
