President Donald Trump and his advisers are debating whether to call off plans to livestream the firing squad execution of the Fort Hood shooter, with Trump having remarked privately that he did not initially know that Nidal Hasan was paralyzed from the waist down, two sources familiar with the discussions told CNN....One of the sources familiar with the discussions pointed to Trump’s deep understanding of imagery as a key reason why he may decide to ditch plans for the livestream. The president has also listened to the argument that a public execution by firing squad could serve as propaganda for foreign adversaries and terrorists to try to paint Hasan as a martyr, a Trump adviser told CNN.
"Deep understanding" that there really isn't any way to make shooting a paralyzed guy look good, even to (most of the) people who want to see live firing squads.
