You're pointing to the corrupt militarized government since 9/11. Fair enough since you don't see the problem as black people see it. They protest, not just the injustice they've lived under this same government you are talking about, but their grief goes back since slavery, and the historical icons the founding fathers whom themselves owned slaves and treated them unjustly and with cruelty.
Contrary to what you said, black people ARE taking a knee protesting many things, including the national anthem which sings of freedom in a nation that isn't free, protesting their systematic murder and incarceration by the State, and for being put down and degraded as a race throughout history and today.
Your refernce in the video to Eric Garner's wife and daughter is another unjustified twist. They were refering to police brutality when it came to their case. They are not going to play the race card in a legal matter when clear evidence of murder was committed. Sticking to that narrative is simpler in court because it is harder to prove a racial motive resulted in murder! The hesitation was all over their faces and voices, but I guess you didn't pick up on that.
Your narrative doesn't hold any justice because you are just another white man looking at this from your own perspective, and not that of colored people.
