Of course not, back then the local law officials shot'em (with water cannons and tear gas) and hauled away the bodies before they could shout 'queers against Vietnam' or some bullsh@t and burn the American flag. Violence and looting was not as tolerated as today.
I'm sure a few are still hiding out in Canada, Cuba, or some third-world sh@thole if they aren't working for the Obama administration or a University where your kids attend.
And don't confuse these reprobates and other anarchists with the peaceful non-violent marches of MLK. They have been riding on the coat tail of MLK and the black movement for years. The blacks have been hi-jacked and used by them. Some are beginning to notice Blacks are no better off, not even close to MLK and grandma's generation in terms of family and moral values.
Obama is just the spawn of the generation depicted in your photos.
And they released the hounds.
