Skimmed some of the comments, but the racist anti President Obama comments are just too offensive. Obama didn't start this or encourage it, it's a product of right now social media and the fact that is it difficult to now buy a cell phone without a camera/video device. My understanding is that one of the slain cops is black. America has a gun issue that we've not dealt with- over 2500 people have died from guns in this country since the Orlando shooting last month. We also have many communities where there are no problems and I'm proud of the Unity March in Anchorage. Many of the protesters I saw in videos of Baton Rouge were white. However if many of you see this as an opportunity to bash the President, most likely because you weren't taught to respect the office, then do what you have to, but your era of exclusive privilege is coming to an end. This is a national tragedy and the President has stated as much.
