Then come the news stories flesh out the details, but cannot answer the "why" questions.
The horrific nature of this man's death is mind-boggling. If the message he scrawled indeed translates to "no more severed heads," the choice of dying by beheading is unfathomable.
Perhaps the man himself had been involved in beheadings, and was confessing his own sins with his final act. Or maybe he has lost a loved one trough beheading in Mexico and wants to bring renewed focus to this brutal means of killing. Whatever the reason, his actions certainly have focused attention on the tragedy of death by decapitation in a far different way than the ISIS beheadings of late.
