Tricia,
Sorry, but Alex Hunter's affidavit didn't state that Burke did not do it. The affidavit states that Burke was a witness and not a suspect, nothing more.
The affidavit, actually written by Lin Wood and merely signed by Alex Hunter, was fraudulent because it intentionally misled the public into believing exactly what you stated in your post -- that Burke didn't do it. However, that affidavit does NOT clear Burke, but the tricky wording in it tends to make the public believe just the opposite. Please note that Hunter did not use the word "cleared" in the affidavit.
Hunter has never said that Burke was cleared. Neither has any other Boulder authority ever say Burke has been cleared. They all use tricky phrases to make it appear Burke has been cleared -- just as Hunter did.
