Well, the other games already desensitized gamers enough to where it's now acceptable to play a terrorist, which would be unthinkable a decade ago. No, I don't think it'll turn gamers into terrorists, but it does contribute to indifference to other people's suffering and to moral relativism when re-enacting the real murder of real people is acceptable to play for entertainment.
I think the point there was if they're just criminals, they don't have any particular reason to kill you if you don't resist, whereas if they're terrorists, they probably are there to kill you. Feel free to use that in you next case.
