Fuck the shield. If you really want to hit him, you gotta go for his soft targets. Nothing ever changes until it effects those in power, and the current one in power has enough money to deal with anything… Except the things that money can’t buy.
If someone is pushed to the point that they are willing to commit murder, they likely aren’t terribly concerned about the associates of the victim regardless of age, because every war has casualties. And, if the victim’s suffering is the point, then they wouldn’t be the target at all, and everyone close to the victim that should be worried.

If more Luigi’s figured that out… Well, it’d be interesting to see.
