What operational info, if any, has been released that would make service members and their families any more worried about retaliation than they ordinarily are, given the nature of their jobs? Or is this just the latest wave of swamp fever sweeping through the wingnut camp?
Why don't you ask your ****ing mental giant hero, aka "Plugs" Biden, about OPSEC and what it means. Now if I were someone about to undergo Sudden Jihad Syndrome, who would I take my ire out upon and detonate in order to gain some Muslim "street cred" and ensure my 72 virgins in paradise?
Attack the Vinson? Bit difficult, and even a car full of boom-boom on the pier or a zodiac around North Island ain't gonna do much damage to a 90,000 ton supercarrier.
But a single (or couple) of SEALs or their family members? Much harder to protect for a long period of time. Much easier to identify. Remember, we've got US CITIZENS who are identifying interrogators at GITMO, much to the delight of Johnny Jihadist. SEALs are good at keeping secrets and not drawing attention to themselves, but any idiot at PSD or out in town can let shit slip and put a BIG target on the back of an operator and their family.
I'll give you a personal, real-life example: when I was on the boats, ALL mail which was addressed to the boat was placed in shred/burn bags, especially when the boat was deployed. This served several purposes: first, it concealed ship's movements. Second, it concealed who was on what boat or what they did, for both professional and personal security. And AFAIK, they still do that.
