About a generaton ago, the JWs leaders' stance was that a JW could defend themself--John 15:13 ("The Watchtower," June 1, 1968, p.347). It was their expanded rules about worldliness that prevented JWs from being able to work for the government, including the police and military and defend others.
The JWs leaders still have expanded ideas about worldliness and government involvement. But do the JWs leaders still allow a JW to defend themself or have they changed that to pacifism?
