I attended school for two-years at El Centro College in the early '70s, where part of this took place. The shootings occurred on the parade route- indeed, just over 1000-feet from- where President John Kennedy was assassinated in 1963.
I'm getting numb about this stuff. I don't condone violence, but as an observer, I think the US justice system- indeed, the whole US government- has become so corrupt that anarchy appears to be breaking out, and may be signalling an era of guerrilla civil-war. It was John Kennedy who said, "Those who make peaceful revolution impossible will make violent revolution inevitable."
I've already read comparisons of this event to the beginnings of the Ukrainian revolution, which began in 2013, and resulted in the downfall of, and installation of a new, government. I don't think this is about guns, or race, or even police overzealousness, but is more broadly about political tyranny. The US government needs to seriously wake up to the needs of its people, or else possibly face Kennedy's prophesy.
