I finally got around to watching that video interview with the grandfather of one of the criminals. I certainly wish they had asked him, and provided the video of his answer, "What would you do if you were confronted by three masked intruders who had broken into your home?"
To be consistent with what he is shown saying in the video interview, his answer would have had to be something like this: "Hi guys. Nice ninja outfits, especially the masks. You know, you can get "punished" for this burglary thing, right? Do you have any weapons on you, besides fists and feet? Exactly what are they so I can determine what weapon I will use to protect myself should the need arise. Speaking of that, are you intending to inflict grievous bodily injury upon me? If so, I may have to go get a firearm, and, I'm warning you, I may use it if you answered the previous question in the affirmative, though if you only have weapons like knives and brass knuckles I would attempt to shoot only to wound. Now go about your business and have a nice day!"
That would likely not turn out well for him. He's as stupid as his dead criminal grandson.
