I don't think it is the stance of Witnesses that God protects you, even from death, murder, or crime while you are out in the ministry and that you can go anywhere without consequence.
There was a case in Mexico where 4 Witnesses were murdered when they called on the house of a drug lord. Also, Al-Qaeda in the Philippines beheaded several witnesses and sent their severed heads to the local Kingdom Hall as a warning to stay away from their part of the island. These were the same zealots that had several Americans and Europeans kidnapped for several years and the finally the U.S. sent in Navy Seals to rescue them. Hopefully, they killed all those monsters.
