I dunno man that looks like the system being successful to me. You read the criminal bulletin?
Drone pilot discharged for schizophrenia who goes off his meds, has a gun, calls the sheriff's office and complains that the "3 stones" attacked him while overseas, mentions he's got a gun that he won't use on himself but will absolutely use on others, cops put him under surveillance and wrap him up as soon as they have a justification.
It is understandably hard to use mental health as an excuse to abrogate someone's rights. They need to be a demonstrable threat to the health and safety of themselves or others before you can even put them in front of a magistrate. Take away their guns? Mmmmyeah that almost never happens before they use them.
I am right there with John Oliver and the rest of the media watchdogs about stochastic terrorism
But the terrible heinous broken system seems to have mostly worked with this one.
