We have some very very deep social dysfunctions in this country that nobody does anything about, doesn't care about, doesn't lift a finger to solve and chooses not to know about.
Worse, the social insurance programs supported by some degree even by conservative administrations in Europe and that really do save millions from degradation and desperation are looked upon in America as welfare giveaways and evil "entitlements."
I am not underestimating or downplaying the barbaric murders in Texas by any means. But...the problem with the gaping hole opened by round the clock cable news is that it radically distorts our perspective and does nothing to help us understand the real world around us. Nor does it contribute to any solutions as it feeds off fear, ignorance and sensationalism.
If we didn't spend a trillion dollars a year on the military (and that's a conservative estimate) and instead invested just 20% of that yearly in urban hotspots and rural no mans lands, you would see most of the above numbers begin to drop. Good luck with that.
