And yes, the witnesses baptize convicted and suspected murderers. They have special assigned brothers who study with prisoners.
Do you (or anyone else here) know anyone who's worked with convicts, especially convicted murderers?
Years ago, I did a series of articles on capital punishment. One of that series involved interviewing people on death row. Coincidentally they were all innocent, even the guy who left church a few minutes early and shot and killed three people in front of almost the entire congregation! He'd been on death row for years and if I hadn't been familiar with his case, I think he might have convinced me. Anyway, nearly all of these guys had Bibles in their cells and read them...religiously. So I wonder if someone on death row could be baptized into the WTS?
Another thing, if I understand JW doctrine correctly, can't someone repent at the time of resurrection? One of the publishers back in the 70s told me that all those who are alive at Armageddon will be able to choose between Satan and Jehovah -- and those who side with Jehovah will be saved. Based on what I've heard since leads me to think that's not entirely true. But if a murderer is executed, then comes forth in the resurrection, will he be saved if he's had a complete change of heart?
