His conviction has been 'reduced' or rather amended. I assume this means he now needs to be sentenced for the 'new' conviction?
do you think him doing already 3 years might be it,? or as you say another sentence could start again , maybe out in 12 months , hope he gets out this year , he done enough time for killing a wounded enemy , who of prob died anyway in that shit hole of a place .!! Hopefully a lesser sentence which he'll have already served. It makes sense.
