In summary
The evidence against Hunter in the gun case appears strong, but it would be very unlikely to have been brought if his name was Hunter Smith. Politics has clearly affected the prosecution’s decisions. But that doesn’t mean their decisions are indefensible, and Hunter’s choices mattered here too.
