here's some info on the situation:
http://www.jwfiles.com/malawi.htm
in crisis on conscience by raymond franz, he details everything and includes letters that went back and forth b/t the mexican brothers and the bethel in malawi, the mexican jws were ready to stop bribing officials to get their military service card b/c they felt it was worse than what the jws in malawi were getting massacred for...which was true, and the governing body was split on the decision on what the jws in malawi could and couldn't do and by the time the killings started, making a change in policy would've made the wtbts look bad, a governing body member was even quoted saying, 'if we're wrong, at least they are dying for righteousness sake' (double check that, it's from what i remember).
so they had a really brazen attitude and turned a blind eye.
if you were in the jws in the 70's, they had us all writing letters to the king of malawi to stop the killings.....i remember staying up night after night writing letters over and over again when i was five or six years old.
i faded four years before reading or finding out about this (i've been out 8 years) and it was really upsetting....a prayer at every assembly included, 'help our brothers in malawi', it was very high profile at the time, then feels like it was swept under the rug real quickly....against the usualy wtbts track record to go over and over it as how 'we triumphed against them' kind of thing.
rwanda got the publicity b/c it wasn't a wtbts flip decision that hurt the people there.
but the chapters in crisis of conscience bring it all out since franz had the letters and correspondence in his possession.
