I can tell you one of the most important facts. The killing of King opened a lot of White peoples eyes to the suffering and the injustice that was being placed on the black people. If you search Martin Luther King Jr. on Wikipedia, That is a good place to start. You can also Google The Civil Rights Movement of 1968 and that will give you plenty of websites to research
This probably won't help you but keep it in the back of your head: the person who had the most to gain by MLK's death due to his radically different views on racial equality was Jesse Jackson.
MLK spoke out publically about the injustices of war at the hands of the US government and the war lobbiest who saw their potential profits fall if he was successfull.
A higher percentage of on the ground soldiers (grunts) were predominately black.
If those young men refused the draft in great numbers, then the US could have easily not carried on in Vietnam. In other words, bad for business.
It indicates the evil of conservatism.
I NEED websites,books, documents, etc. entailing the answer! I'm having trouble finding some.
