Either way you will have made yourself a pariah among your peers and pretty much just contributed to the chilling of unguarded speech even among comrades over a pretty minor law (and regardless of what LITS says- it's underage drinking- which is right up there with speeding which I assume he is not advocating you also would turn someone in for).
Surely LITS also recognizes that his follow up about "what do you do when he lies" is a completely different offense?
There is a difference because we say there is. Much as we say "let the cadets or midshipmen handle it" there is a limit to that. They are in a training environment. An alcohol offense would not end their career, especially as a cadet/midshipman. Would they lose Christmas leave? Maybe. Would this come back to bite them later? No.
Bruno of course understands that the "offense" at an academy is different from one in the fleet. I'm sure that USNA is no different from CGA, your cadet file is sealed when you graduate. While I understand you didn't go to an academy Bruno, I would assume you understand the concept of the fact that being on leave does NOT mean the midshipman is not longer subject to the rules and regulations of not only the Naval Academy, the the U.S. Navy. What grounds would he be reported? On the same grounds that a cadet is reported for wearing civilian attire within 100 miles of the Coast Guard Academy....because they are violating a regulation.
As I write this, I'm on leave. That does not mean I am going to put on my uniform and run to the next political rally in my area. There are rules that I have to follow, even if I'm not in my office, even if I'm not on a ship. The government is paying me while I'm on leave, and I owe it to the government and my branch of the service to follow the rules.
Maybe standards are different at the Naval Academy. When I was a firstie (senior) I had a classmate in my company who was walking the line. He worked in a division that handled drill for the company. He asked the Company Commander (also our classmate), if he could go out to get ice cream for the company after drill as a little "morale". The company commander said no. The classmate when out anyway. He was reported for disobeying an order, and he was masted. He didn't break a LAW. He did something contrary to what his cadet chain of command said.
Do you think he graduated? Do you think he's an officer in the Coast Guard today? No. That cadet showed an inability to follow orders, and at that stage, could he be expected to enforce any kind of rules? Probably not. The company commander got some grief from classmates, but she had made her decision, and while unpopular at the time, followed through. He threw almost four years away because he did not do the right thing...and he didn't even break a law. It wasn't even an honor violation. Had he been "checked" earlier in his cadet career, maybe he would have learned his lesson before it resulted in is dismissal.
Now, Bruno and Memphis might think that this is a minor offense, disobeying the orders of a fellow cadet, a classmate even. However, I would maintain that you have to draw the line.
I'm inport OOD during a patrol in the Florida Straits. I have a Coast Guardsman who gets into a fight at a bar, and makes a run for it. He leaves his ID behind. The base OOD brings his ID and lets me know what's happening. Is it worth taking to the command? Sure. I'm on watch, the good order and discipline of the cutter is my responsibility. That was at 2 a.m. The XO was immediately informed. Was he much older than a midshipman? Nope.
Where do you draw the line? When does it become an issue that needs to be addressed? If the OOD is being called at 2 a.m. to FIND a member of the crew, then it's probably gotten to that level, especially when that missing member was scheduled to be helm pulling out the following morning (which I did not have him do). But some would have you believe that, in the name of that person's career, don't take action. We could apply that "trigger" to just about everything....maybe exclude capital crimes.
These are the questions you will have to answer for yourself. I do not agree with the general idea of Bruno and Memphis that if it's minor sweep it under the rug. There is more than one example of crisis within organizations, like the Navy and Army, which a minor event was ignored and it grew. Abu Ghrab, Tailhood, Tillman, the list goes on and on. Small issues can snow ball. I'm not saying underage drinking would, however a culture developed at a unit to "ignore" various offenses in order to save the offenders careers, often end with someone losing their job...whether they have an oak leaf, eagle, or star on their shoulders or large stripes on their sleeves.
That's my opinion. Because you're not a midshipman yet, you will just need to remember what it looks like. When you are a midshipman, that's when those questions become more difficult to answer.
