If I could just drag us back on topic...
Whether you trust the police or not: whenever you are involved in a death (whether it's a clear accident or an accident that could be a murder), you will be obliged to make a statement to the police at least once, which Gabe did. And most people at that point don't have a lawyer present - it usually happens right after the incident.
It's the fact that Gabe went back a SECOND time and started giving "more info" that is a little weird. And then - in that second interview - he told things that were later proved to be lies (ex: about the "strong current" - but then the police found out he had gone out after the accident and bought a book about the site that warned of strong currents).
As an American lawyer, I would have participated in the first interview without counsel. But when I decided I needed to go back and "clear things up", I would have asked a lawyer for advice first and probably taken him/her with me to the interview. Sure, I think that way because I'm a lawyer. But in fact nowadays - due to all the crime shows on American TV - the average American knows not to talk to the police without an attorney present.
So this means Gabe was either very stupid or very arrogant. And I suspect it's the latter. Why?
(Oh, I hesitate here, thinking of the flaming I'm going to get from my fellow Americans...) After 17 years living outside the U.S., the arrogance of Americans abroad continues to amaze me. So many think that the governments/police of other countries are completely incompetent, compared to the U.S. (And I confess, I've thought that myself on some occasions.) This is not the first time an American has thought this way and ended up in a bad situation.
So yeah, I think that Gabe was arrogant enough to think he could convince the Queensland police that it was merely a sad accident. And then he tripped himself up with his conflicting statements and the alarm bells (rightly) went off.
Does this make him guilty? No. But it did open the door to the police investigation, where they found even more bizarre inconsistencies that - when put all together - suggest this is more than an accident. (If you don't know what I mean, you should read slowly and at one sitting K_Girl's excellent summary of the case on the other thread.)
Frankly, once you read her summary, you realise that the police in ANY country would be very suspicious of his story. Where it will go from here, we'll see.
Just my 2 cents.
