Kim Jong-un's Barbaric Purge of 'Unsound' Military Brass

[The Mikado]

I'd take firing squad (actually, probably the easiest way to go out of major execution methods) over being blown up by a mortar any day.

That said, military purges in N. Korea are only vaguely newsworthy at this point.  It's to be expected.  Frankly, the macabre execution method is messy but at the same time is still far superior to traditional methods like hanging or electrocution.
