00s just became mob rule via social mechanisms and manipulation; cliquish behavior is not something you can shoot or detonate, so we're stuck with people taking out their frustrations on children at school and anybody unsuspecting. The dejected are only going after targets they can reach (a tragic, but logical outcome).
There was one aspiring vigilante in the last few years who drove across the country to assassinate some scummy judge or something and was immediately caught while doing recon. His mistake was going after someone afforded protection. Everything is political and treated as terrorism. It's too risky to vote from the rooftops these days; there are an increasingly-infinite number of ways to fail.
