Kieth,
      The very reason for reporting is to draw attention to the event.
The perpetrators are carrying out the act in the name of their cause.
Reporting it gives the perpetrators the publicity they are seeking for their cause.
Nowhere do I say or imply that the news should be suppressed.
Of course normal decent people are upset by it,other people may think it a victory for their own twisted version of reality and go on to do similar things themselves.
