The police had the means and the equipment to make contact with the perp.
I believe they were acting in accordance to their faith. Hoping that someone could help resolve this without violence.
Times have changed. Just as the result of the events of 9/11 that aircraft hijackings are now considered terrorist attacks, any take-over of a school or university will not be considered a hostage situation but rather a killing field.
I only lurked this thread yesterday, but the references of hostages in these school take-overs shows naivete towards the current criminal elements in our midst.
