I would encourage you to read the documents you cited.
To wit, your general commentary is along the lines we can do nothing about guns and in regard to anything else, the prescription offered is just lock more people up.
In contrast, one of the articles you cited said:
In tackling the present crisis, it is thus a clear mistake to focus only on police brutality, and it is fatuous to attribute it all to white racism. Black policemen were involved in both the South Carolina and Baltimore killings. Coming from the inner-city majority terrorized by the thug culture minority, they are, sadly, as likely to be brutal in their policing as white officers.
We see this in stark detail in the chronic violence of New York’s Rikers Island correction officers, the leadership and majority of whom are black. We see it also in the maternal rage of Toya Graham, the Baltimore single mom whose abusive reprimand of her son, a video of which quickly went viral, reflects both her fear of losing him to the street and her desperate, though counterproductive, mode of rearing her fatherless son.
WHAT is to be done? On the police side of the crisis, there should be immediate implementation of the sensible recommendations of President Obama’s Task Force on 21st Century Policing, including more community policing; making the use of violence a last resort; greater transparency and independent investigation of all police killings; an end to racial profiling; the use of body cameras; reduced use of the police in school disputes; and fundamental changes in officer training aimed at greater knowledge of, and respect for, inner-city neighborhoods.
Accompanying this should be a drastic reduction in the youth incarceration rate, which President Obama can make a dent in immediately by pardoning the many thousands of nonviolent youths who have been unfairly imprisoned and whose incarceration merely increases their likelihood of becoming violent.
In regard to black youth, the government must begin the chemical detoxification of ghetto neighborhoods in light of the now well-documented relation between toxic exposure and youth criminality. Further, there should be an immediate scaling up of the many federal and state programs for children and youth that have been shown to work: child care from the prenatal to pre-K stages, such as Head Start and the nurse-family partnership program; after-school programs to keep boys from the lure of the street and to provide educational enrichment as well as badly needed male role models; community-based programs that focus on enhancing life skills and providing short-term, entry-level employment; and continued expansion of successful charter school systems.
Two things. It is a mistake to concentrate solely on the police brutality. I agree; but that doesn't mean that policing policy gets a pass. Indeed, it is the first real step that those who are vulnerable to recruitment by gangs will see that suggests that society in general cares. It is also something that government can do unilaterally as LEO is hired by local government and under the direction of local policy makers.
Second, above someone posted a list of the things they said were the goals of the black lives movement. If you compare that list with that of the Presidents report from the 21st Century task force on policing (link above) you'll see the prescription is virtually the same if not identical.
As the article excerpt posted also notes, things like the self-inflicted by the conservatives in Flint in forwarding their agenda of cost cutting at any cost, the toxicity of the communities in which these folks are living also has to be addressed.
Have any of these issues been addressed positively by any republican legislature in any state. We've seen in Michigan, the GOP dominated legislature and governor have done nothing but exacerbate the problem literally poisoning the people. I've seen a bit of progressive understanding in Ohio where they did expand Obamacare with the support of Gov. Kasich. But in Kansas, home of the Koch brothers empire, public services and public budgets have been slashed to make for enormous tax cuts, the value of which accrued only to folks like the Koch's as there was no trickle down.
The current tax cut law proposed nationally seems to be based on the importance the GOP and conservatives place upon adding zeros to the bottom line of the wealthiest folks in the country and out ... some where upwards of 50 percent of the corporate tax cuts will accrue to foreign investors outside the US.
Indeed, if you actually buy all the information and proposals contained in the links you posted, you would have to back off and be critical of the tax-cut obsessed Republican legislative agendas because frankly it costs money to do things and the only thing that the republicans in congress and their administrations seem intent on doing is cutting taxes and doing nothing while ramping up the culture wars.
But they were good links; they didn't support your point of view nearly as much as you think, but you ought to read more and take their message to heart.
