Actually ... That's VERY misleading.

What IS happening, is that the military is allowing women to officially have combat roles.

That change is bringing up the QUESTION of whether there will be a change, to make women eligible for the draft.  Neither the President nor Congress has even looked at that question yet.

I've just read two reports stating that the female shooter had pledged her allegiance to ISIS. I imagine her husband had as well. My guess is that their motive was to kill Americans as that seems to be the daily chant of ISIS.

You need a motive for killing even 1 person.

IMO ... They were planning on getting away with it.  The only reason for destroying their electronic "footsteps" would be to prevent the authorities from tracking them down afterwards.
