So joining the coast guard is like going to prison?
Depends on the specific job you have while in the CG.
Again, your ignorance, self inflicted at this point, is a detriment to your position.
Those two Coasties may have had authorization to go about in public while armed. If they are GI guns they must have authorization. Of course, they could have lifted the gats just to pack heat and look all official and the like.
Now, do you have/hold a "civic" duty to "see something, report something"? Ya got a cell phone? A crime could be being committed before your very eyes. Heck, they could be ready to snap and start dropping innocent civilians at any moment.
Take the cop mentality to heart and be a good citizen and make the call. If those two Coasties are on the up-n-up all will be good, no? A little inconvenience for the safety of all is tolerated these days. What's the big deal? What, you don't want kids to be safe? Ya got something against kids?
Whether or not a couple of Coasties were following orders, or not, while packing a GI pistol is a non-issue as far as I am concerned.
