That is a slippery ******* slope there my friend.I feel like it should be the law that if a prominent whistleblower is found dead, everyone they blew the whistle on should just be declared guilty of their murder automatically.
There should be a massive, in depth investigation where in the whistle blowed are considered the prime suspects: but not automatically guilty. Maybe the cars brake lines failed due to actual poor maintenance, and not a clever ruse.
