The only reason I like star wars was cause storm troopers looked cool and from there I would watch the movies , series , collect action figure <| sep |> Nothing of what you have said is true . And it ' s important to point out this misinformation you are spreading . Number 1 . It IS native land , according to the Fort Laramy treaty of 1851 , that yes , HAS been ratified since , but despite that , the area in question still remains very much property of the Standing Rock Sioux Tribe . This has been confirmed by , amongst others , Tom Disselhorst , a former federal Indian law professor at United Tribes Technical college , and Grant Christensen , an assistant professor at the University of North Dakota school of law , with the statement The supremacy clause of the US constitution makes any treaty the ' supreme law of the land ' and the terms of the treaties remains in place unless specifically repealed by congress . Second , the idea that the pipeline won ' t pollute . This is also totally false . While it is true that trucks do create pollution by their exhaust and tearing up of asphalt , it is fully possible today to use bio fueled trucks , which would reduce pollution tremendously . Not likely , but fully possible . Pipelines however spill , all the time , Wikipedia has a list , feel free to look it up . I ' m on mobilePlacing a pipeline across drinking water is simply disastrous as all you would need is a single spill , to potentially harm a tremendous amount of people . Lastly about the concussion grenade the police threw at the girl . It ' s important to differentiate between an actual concussion grenade , the mk 3 , which is a lethal grenade used by the US military , and the stun grenade , the M 84 usually , also known as the flashbang . The latter is in wide use by police forces all over the world , and this is the type grenade we are talking about . It is true that this grenade does not fragment its EXTERNAL casing . That casing is designed with a grid , at least the M 84 is , to allow the flash and sound from its internal casing , that does fragment , through . Due to this design , it is considered nonlethal , HOWEVER , evidence speaks against it , when it detonates at a close range . And we saw this in 2014 , in Ukraine , during the revolution there at the time , when a man tried to pick one up , that detonated in his hand , leading to a loss of most of his hand . In other words , a very similar example . This , and another 10 documented deaths or serious injury by the stun grenade can be found in its Wikipedia page .
