Wouldn't have been the first time, though. Remember the waiter in Atlantic City that Chris and Paulie killed? And in that case, Chris knew that he wasn't the only one who knew about it. For all he knew, Paulie could get the Feds to promise immunity from prosecution and then tell about the waiter murder. If Chris was ever worried about being found out about the murder of a civilian, it would have been then.

All I'm saying is there was a precedent. I haven't made up my mind if Chris was a rat when he died. We'll never know for sure, of course. All we can do is do what we're doing now.
