Here is the first part of the story and I caught the final this morning.
It seems the VA was unable to make a case... by not making a case I mean they could not even prove he had placed the flag, it also came out in court the arresting officer violated his Miranda Rights, and his First Amendment. Seems this was this was retaliation as the group this Vet was a member of Won a Suit against the VA.
Ahh yes the good old corrupt VA, seems there needs to be a Purge done I hope Trump gets to it soon.
