If you haven't seen this post before (it was posted on this day last year and this day the year before that), it's a reminder that protesting a wrong your government is doing is legal - it is part of our democracy. And when 100,000 people do it, as they did on this day in 1970, it sends a message.

As an outgrowth to the violence that met the anti-War protests at Kent and Jackson State Universities only a few days earlier, a mass demonstration and protest to the Vietnam War and our incursion into Cambodia on April 30th was organized and a march on Washington was held on May 9th.

It was the biggest demonstration of its kind, and the most peaceful. This was the demonstration made somewhat famous by the presence of President Nixon, walking through the crowd unannounced and without Secret Service in the middle of the night, talking with protesters.

News reports remarked Nixon thought the exchange with the demonstrators was "interesting". At a time when the word "interesting" could either mean enthusiasm, revulsion or the Chinese Curse - it was hard to pin down exactly what Nixon meant. But suffice to say, this demonstration brought mass opposition to the Vietnam War very much to the forefront.

Here is a special broadcast as presented by NBC News on May 9,1970.

A month to the day after the tragic shootings at Columbine High, another in a long line of gun violence at school happened, this time at Heritage High in Conyers Georgia outside Atlanta. The shooter, a Sophomore by the name of Thomas Solomon, distraught over a recent breakup, decided it was a good idea to go maladroit and take his grief out on unsuspecting kids who were just trying to get through the school year in one piece. The result was the wounding of six students and a distraught Solomon, tackled to the ground as he contemplated pulling the trigger on himself. And once again, the hands of the nation were firmly holding up shocked heads as yet another school shooting unfolded on live TV.

And so the news of that day in 1999 was pretty much taken over by that event, with words of shock, proclamations and resolutions to end gun violence in our schools being voiced on Capitol Hill.

And meanwhile, Chemical giants F. Hoffman La Roche and BASF were handed hefty fines over the Vitamin Scandal which saw them rigging prices on Vitamin C among other supplements. Interesting when you consider BASF was very big in the "Arbeit Macht Frei" movement in the 1930's and '40's. But that's another whole story, along with Bayer. They giveth, they taketh away.

And so May 20, 1999 as presented by CBS Radio News.

(Vietnam War Protest May 9,1970 - The reflecting pool was going into overflow)

With the recent deaths at Kent State still sending shock waves all over the country, over 100,000 protesters converged on Washington D.C. and held the largest Anti-War protest rally yet. For the most part it was a peaceful rally. It was during this rally that President Nixon snuck out of the White House at five in the morning for a much publicized mingle with the crowd. Our recent turn of events in Cambodia made protesting the war an almost daily occurrence, with demonstrations going on all over the county.

How long these rally's would stay peaceful was only a matter of time, and less than four days later the outbreak of violence at Jackson State would add another dimension in the protest movement.

Here is an NBC Special report on the Washington D.D. Protest as it was held on that day, May 1970.
