Thank you for the link Dim Tin.
Martin Luther King was one of the people who accomplished so much for the Afro-American, and unfortunately, like so many trying to improve the lives of others, lost his own.
Some people do not bother with links Dim Tin so I hope that you do not mind my posting the Psalm and the picture in the link.
It is fitting to note that Mahatma Gandhi is displayed in the photo on the wall.

Psalms 15
Lord, who can be trusted with power,
and who may act in your place?
Those with a passion for justice,
who speak the truth from their hearts;
who have let go of selfish interests
and grown beyond their own lives;
who see the wretched as their family
and the poor as their flesh and blood.
They alone are impartial
and worthy of the people's trust.
Their compassion lights up the whole earth,
and their kindness endures forever.
