I do worry about that. Some poor innocent Sikh is very likely to find his mandatory headwrap in a few crosshairs, and he ain't the problem.
Most of the pros won't be machine-gunning anybody; a professional gets others to do his dying for him. Anyone young and pumped-up enough to try this kind of stuff is far more likely to be found on sundry college campuses and in jails.
RW, I won't really be looking for turbans, that was just a turn of phrase. I'll be looking for muzzle flashes and stuff zinging through the air my direction. Those are some of the classic warning signs that your day is not going to be a good one...
Whether it zips, zings, buzzes, or whooshes, maybe they'll all come out at once and go down in a blaze of glory. It might restore a measure of honor to their names, although certainly not enough to balance their attacks on undefended children and families.
