That having been said.
There is a point where this is not feasible. Some people do not want to graciously accept leniency, but instead see it as a weakness to exploit. These rules can be twisted back against us. As we can see in Baghdad, Baathist dead enders are firing mortars from civilian neighborhoods because they know we won't fire back. We could fire back, but then we'd be hitting civilian areas.
It's a very delicate balance, but overall it is best that we take every effort to be in the right. We should also understand that we're not perfect. We often put our people in very, very dicey situations and expect perfect performance, but that's neither realistic nor fair. Given how careful we have been in every other aspect, we should at least give our guys the benefit of the doubt.
