@Penner: I like your point of view here-- and how you sided with Laura. It was intended that she be an antagonist at this point but that her reasons and resolve challenge the audience's morals. In fact, just about every major Gerry vs. Laura scene in the series tries to rattle your beliefs and get you to pick sides with out handing you a "right" answer.
I'm going to spoiler this next bit, though--
The only thing I disagree with you on is the idea of the US military wiping out civilians because one of them is a hostile witness-- or even because of a "witness" being present. The military wasn't considered a force of evil here-- in fact, they would hold up the bombing as long as there were civilians at risk.
It took Billy assuring his handlers at InGen that they would be off the island at a certain time for the company to convince the military to be able to proceed. He needed the bombing to help obscure the evidence of his betrayal.
The military wasn't in any kind of wetwork cahoots with InGen to destroy witnesses. If Sorkin hadn't been so difficult, then the military would have sent in a rescue team of their own. And if Billy hadn't lied and gone rogue, then even InGen would have sent another team.
That's SINAZ. He fights for the "Users."
