I think most people in power do things that the rest of us would be in jail for if we did them. King, Kennedy, Johnson, Nixon, Clinton. All of them did something, many were felonies. But this stuff with King is beyond illegal. It shows what a hypocrite and miserable human being he was. His character is now in question and his now famous words are hollow and meaningless.
The appropriate thing to do now is to remove his name from anything, including the national holiday, street signs, and remove statues of him from all public places. If someone still foolishly wants to admire him, they are free to do so in private.
Now we'll see if the government has the balls to do anything. They remove statues of Stephen Foster and take down confederate flags because some snowflakes' feelings are hurt. But I'll wager that in typical fashion, the government (Socialists/Dems) will do nothing and will ignore this. And people will let them get away with it because they're afraid to say anything in fear that it would be viewed as racist. Saying and doing nothing would be racist! That's who we are now, thanks to Obama and his cronies.
