Both Jesus of Nazareth and Martin Luther King, Jr had ministries that spanned years and ended in roughly the same way. MLK's was longer than Jesus', but Jesus seemed to pack a lot more in a shorter period of time.
"On the one hand we are called to play the good Samaritan on life's roadside; but that will be only an initial act. One day we must come to see that the whole Jericho road must be transformed so that men and women will not be constantly beaten and robbed as they make their journey on life's highway. True compassion is more than flinging a coin to a beggar; it is not haphazard and superficial. It comes to see that an edifice which produces beggars needs restructuring. A true revolution of values will soon look uneasily on the glaring contrast of poverty and wealth."It was the 1967 version of overturning the money changers' tables.

They were right. It was dangerous for Jesus and it was dangerous for MLK.
