There should be some consequence
What about all the people in every major city in America who know of a crime being committed outside their house but don't come forward with it?
There are risks involved in opening your mouth. Say this is part of a bigger picture, say there are people above these two that ordered this bombing. These higher ups find out that this dude went to the police and that is how the bombers got caught. So now the higher ups come after and kill this guy.
Is that what would happen? I have no idea, but it is reason enough to keep quiet, isn't it? People keep quiet about crimes every day.
ETA: Most people have seen someone, a stranger or a friend, get in a car after too many drinks. If that person gets in a wreck, should you suffer consequences as an accessory? I mean, you watched them drive off but didn't call the police...
