The media does more to hurt the security of the US and deployed troops than any other organization. To advertise or identify weaknesses in US security should be a criminal act. That being said I believe the government does not need to interrogate people who provide or seek advanced dive training. As September 11th illustrated, these knuckleheads don’t need high speed training, just enough to get by. But if they need to investigate they should do it quietly so as not to impose on the rights of US citizens and, more importantly, not to disclose the object of the investigation.
