Like The Turk says "Relax Tom, we know your not in the muscle end of the family etc." The same was said by Clemenza to Sonny about Michael in the kitchen when Mike wanted to visit Kay in the city after the Don was shot. So until Mike shot Sollozzo and McCluskey he was not expected to make any bones and Hagen of course never did. Fredo is left to the imagination as far as bones go, but being the Don's son I doubt if he had to actually kill someone in the classic make your bones sense.
