(Seattle, WA)  --  The president of the Seattle Police Officers Guild says he's stepping down, following a controversial social-media post on the deadly shootings of five Dallas police officers.  Guild president Ron Smith posted a Facebook message last week which read "The hatred of law enforcement by a minority movement is disgusting."  Smith says he posted the message in the heat of the moment and didn't mean to offend anyone.  His resignation as Officers Guild president is to take effect July 31st.
