The problem is you can’t excuse a 6 on 1 beating on “tension”. Things are tense between programming and QA here at work, but it doesn’t mean we get a pass if 6 of us programmers wait out in the parking lot and beat the tar out of some QA person with our pocket protectors.
Or, a little more realistic example. Things are tense over in Iraq, but when that group of soldiers snapped and executed that innocent family they were charged. I’m pretty sure the tension between our military and the Iraqi’s is a little more tense than at some LA high school.
