The company behind this pipeline has handled this whole situation with shockingly poor tact. Hey sending your hired thugs after protesters? Not a good look if you're looking for by in from people living around the 1000 or so miles this thing covers. Arrest warrants for press covering the protests? Again, not a good look.
Bitch about "private property" all you like. The reality is with any pipeline project it requires tremendous stakeholder buy in as it's affecting a lot of the land outside of the precious private property some people like to jerk off over.
Like if you're trying not to be a comically evil oil company you probably shouldn't act like one.
