Granted, you might understand it better if you saw the whole movie.
Perhaps a little more "violent" - but the feeling is very much there - "WTF are you doing?" But I was talking to someone about how there is incompetence at work in an area, and, this movie popped into my head.
Particularly the questions about the brief case, the confrontation about the position of the guns, and such things. The questions about the brief case are related to information, information dispensation. And also "amateur night" comments.
The anger isn't about being a badass or showing off, it's because the functionality of the situation is at hand, and this is a major problem - especially when lives are at play, and precious things (money). Etc.
