Think JFK & MLK:
Perhaps they were trying to make a martyr out of him.
Perhaps gun control is not as strict in Sweden as they’d like it.
Perhaps Palme was not as effective in pushing Marxist laws as they wanted.
Like JFK, it was his [HIS] govt that investigated the murder.
BTW why was Christer Pettersson, acquitted AFTER he was convicted [and] identified as the killer by Palme’s wife??? Non of these sites explain that.
