It seems there were at least three or four murders they couldve had him on over the years, and his armed robbery crew, and his gun running schemes to the IRA . The fact that he hasnt had multiple life sentences makes it seem almost impossible he wasnt a protected informant.
I wonder what howie winters reputation is like nowadays? On one hand the guy should be a legend after all his been through and to be free man now. But on the other hand he did testify in open court during the bulger trial.
