The city will settle. As pointed out a couple posts up, the cost of litigation and the risk of losing is too high.
I read elsewhere that while Wilson is named in the suit he actually isn’t being sued. The Brown’s lawyer is smart, knows Wilson certainly would fight it and would take in a massive amount of donations for a legal defense fund to finance top representation.
Wilson is being sued, and so is the police chief. Along with the City of Ferguson, they are named parties, and the plaintiffs are asking for a money judgment against them.
