The skeptic in me questions how 'random' shootings really are. Data suggest they are not. Data contrary to the prevailing narrative are often swept away or conveniently omitted. National news is representing 'mass' shootings (which prior to 2012 were defined as shootings with 5 victims or more, now redefined as 3 victims or more) as 'random'. But in fact, in most cases it is apparent the individual who perpetrated the crime had plenty of motive. Worse, it appears in many cases there was advanced warning that the crime would occur, that authorities were notified, and that there was a failure to act, follow up, or otherwise inhibition of law enforcement to prevent a crime from occurring.
The latter point is especially damning of the system and the narrative. Because it's all built on the conceptual framework that we need government intervention and more of it. If they can't get shit right, right now in the system, why do we think it will get better? Remember this is a government that couldn't turn a profit in a whorehouse. If, instead, shootings are portrayed as random and the police and state are our protectors, then logically, more protection against 'random' violence would be a good thing.
Realistically, violence is not randomly distributed. More police and more laws won't protect us, because what's going on, isn't random at all. With startling accuracy we can predict where most crime happens and who perpetrates it. A more proactive set of policies that includes actually imprisoning and/or eliminating the individuals who are the perpetrators of said 'random' violence, will go a long way towards solving the problem. The problem with the aforementioned solution is that 'random' violence is perpetuated primarily by a certain subset in our society and enforcement of laws against them has been deemed racist.
That represents a genuine problem, because a goodly portion of our society and history was built on the backs of forced/slave labor and we have substantial historical amounts of racism in our past. As such, policies that will disproportionately target individuals belonging to one group (to be brutally honest, young black males) are 'untenable' when carried out by the state. It's a precarious position to be in, because we have a situation where one group commits most of the crime and where we cannot actively police that group due to the abuses in the past. We can't find a way forward, until we find a solution for past mistakes, we can't find a solution for past mistakes, because they are far in the past. It's a Catch-22 of epic proportions.
Frankly, the best solution to these problems isn't tenable. Constructing a self-sufficient society that values hard, honest, work, doesn't glorify easy solutions to problems, and respects strong enforcement of laws - simply won't happen. At least...not without a substantial draw-down of our population numbers. We need to slice our population by about 3/4ths to enact such sweeping social changes. Until Americans give up on Kardashians and 15-minutes of Fame and focus on solving real problems with hard solutions, we're fucked.
