It's odd to find such certainty expressed so willfully, while still grasping around to find the right regs.
I know of no reg that says that an active duty, uniformed officer cannot make a "morals statement" in public. Neither do I think that the rules AS has quoted are the governing ones (even the most recent set), but I'll leave that to AS's "blog power" to sort out.
BTW, you ought to read the damn regs before you post them as support. For instance, section 1003 doesn't quite say what you think, does it?
