Irelands32, No, Roselli was killed for completely different reasons. He was not really a Giancana loyalist so to speak.
In other words, he was NOT a Taylor St. man.

He was direct with Giancana because Giancana INHERITED him from the previous years.

He had been the Outfit's man in Los Angeles. He had a couple of soldier/associates who worked directly under him out there.

He mainly would oversee the Union /Hollywood situation. He also relayed orders to the Los Angeles family. When Chicago said jump, Los Angeles said 'How High'.
