In my experience you shouldn't profile. Not because it is wrong, but because it doesn't work. Hope nobody got hurt. I really should carry a pen again. I used to always keep my space pen in my wallet but it had... an unfortunate incident happen to it. So now I am penless. Next time I'm at the base I'll pick a new one up, they are 10 bucks less there than in civilian stores.
And I would always be especially wary around the younger people, they often don't know or care about consequences. I know a girl that was involved with two other girls 16-17 yo that broke into a liquor store that was closed to rob it. All white girls. So ya can't profile... it doesn't work. Gotta be equally aware of everyone you meet/see... even the little old lady with a walker could go crazy on you.
