VIDEO - Marine Scott Olsen Moments Before He Was Shot By The Oakland Police, Olsen Now In 'Critical' Condition - Home - The Daily Bail
Which of the 3 things you list was Scott Olsen guilty of? Being as close as he was I hope you aren't going to claim it was accidental.
Who is Scott Olsen?
Nobody I have read about is claiming active duty Marines are attending, that doesn't mean some active duty ones don't have opinions (that are quite different than yours) about the 'incident'. Every successful revolution by the 'people' has ended up getting Military support, that is where their loyalties are when push comes to shove. The tipping point comes when they refuse to open fire on civilians.
They did say "the Marines are coming to protect the protestors." It was insinuating that "the Marines were coming", not some Marine Vets were going to be there.
Marines I served with had all kinds of differing opinions on everything. Beer, women, sports teams, politics, religion, movies. Some times we even came to blows over stuff.
Every Revolution? Did the colonies have support from the British army? Nope. Did the British Army have any qualms about firing on civillians... Boston Massacre, Lexington comes to mind. In the case of Occupiers, the police forces will not need the military. Every city they have moved on the Occupiers they have been pushed out farily easy.
