The white liberals are sad because Jessie Jr was a black man caught stealing. It doesn't fit into their story line.
In addition, if Jessie Jr. ever ran for public office again in a black district he would win. All one has to do is look back at the Marion Barry situation where he was smoking crack with prostitutes in a Washington hotel room while mayor of that city. Barry goes to prison comes out and runs for mayor again and amazingly wins. Black people will vote for other blacks even if those elected ultimately harm them.
And the white liberals embolden them.
