I assure you that if your local sheriff thought there was a real possibility that there was a terrorist bomber in your house holding your family hostage he would have his gun drawn. That’s reality.
Yup, it all hinges on the “real possibility” if in fact they had a real possibility I would not complain after the fact. But I would bitterly complain if this was SOP for house to house with no intel indicated the wanted criminal with was on any particular premises.
I'm sorry -- did I miss something??? Was there a terrorist in that house holding those people hostage??? and since when do you rescue a family held hostage by aiming your weapons at the hostages???
