This kind of thing needs to be remembered. Not just for the sake of remembering, but to show that there was and still is an enemy within this country. We can't afford to have this kind of thing happen again in this country. People that destroy in this manner aren't protesting, they are committing war. As such, they should be treated as the enemy combatants that they are.
I agree completely, and think that because of recent events on the political front, people will come to that realization.
Something I realized taking my trip down memory lane via the internet is that many of those who are "retellers" of the story, are presenting it with a sympathetic bias, and romanticizing the events of the time. They present those who were involved with radical, and extremist groups that engaged in criminal and violent acts as folk heroes who were driven to such actions by an oppressive American government.
