Context: If you don't know, the national guard in 1970 fired into a crowd of people who were protesting the Vietnam war. Killing 4 people, 2 protestors and the other 2 were bystanders.

This shows nothing has changed.
If the cause is right and you have to fight. Fight with everything you got I say. Don't let anyone call you crazy for having passion or the guts to stand up to power. It doesn't matter because as this shows, they will vilify you and say whatever they want about you anyway, even just standing at a protest.
