If the system doesn't work; if no one inside the system doesn't fix it; if no one outside of the system with oversight for the system doesn't fix it (government), then what recourse do the people subject to the system have? Most will work to change the system, and pressure government to improve the system...but it's been decades and many systems are not improving, most all are getting worse.
It should be no surprise that victims of the broken system, many who likely tried to work within the system and play by the rules, ended up being denied by the system. And some of those denied by the system, with no other recourse, or sufficient resources to fight within the system, took matters into their own hands using options that were available to them.
I'm surprised we don't see more of this...maybe we will?
