With a bit of research you'd have found that many of them are clearly only coincidental. For example, Tremonte turned himself into the local sheriff after it was discovered that he was into kiddie porn, and then voluntarily resigned his position. Doesn't sound like someone who was framed, does it?
Chaunhan had attempted suicide several times over the past few years, and when she tried it this time she was successful. She called her husband from her motel room and told him what she'd done before she died, and, as she was beginning to suffer the effects of poisoning she ran into the motel hallway yelling that she took cyanide. Again, doesn't sound like someone who was murdered, does it?
Black was killed in a plane crash caused by very poor visibility. Unless BP can control the weather, it's doubtful they had a hand in it.
Sen. Stevens pilot had multiple health problems, and had suffered a stroke not long before the oil spill. He should not have been flying at all. In anticipation of the "whistleblowers", could BP have engineered his stroke, that happened before the oil spill? Seems rather unlikely.
If you dig into some of the others, you'll find out the conspiracy starts to fall apart.
