Seth Rich wasn’t a 5 year old boy found at the bottom of a well. He was a grown man. His parents wishes are irrelevant. If he was the DNC leaker (he likely was),every stone needs to be turned to find it out. Ditto his murder.
But vilifying them for their speaking their mind isn't cool.
Most people in their position would react in the same way.
Wouldn't you feel angry if Obama or Clinton supporters were trying to use the death of one of your loved ones to score political points?
Isn't that human nature?
