A cohesive home with both the mother and father present, where moral values are taught, is more effective than a sad, government-run program.
Which can be torn apart by crime, police brutality, over-policing, or criminalization of being poor; get a parking ticket, fail to pay it, go to jail, lose your job, rinse and repeat.
(A sign seen at a BLM protest sums it up: "You kill our fathers, then make fun of us for not having one")
> where moral values are taught
I'd wager that the vast majority of parents and guardians teach their kids not to lie, cheat, steal, or hurt other people. How much those teachings take root depends a great deal on the child's environment and peer group. Don't believe me? Then why do parents pay so much money for a "good" school district? The moral values they impart should hold even if they live in a "bad" neighborhood, right?
> sad, government-run program
Who said anything about government-run? Churches, community groups and local clubs like the Rotary Club, even police departments (this last one is the government, I'll give you that) run after-school and youth programs to keep kids busy and engaged in productive pursuits.
Secondly, if both parents are working long hours, you need someone to keep an eye on the kids after school. Some people have grandparents or other relatives but not everyone is so lucky (the grandparents themselves might be working long hours; generational poverty is a thing). Absent that support, the external factors I mentioned above begin to dominate.
Again, I don't understand the hate for a movement that, at its core, claims to want to hold government servants accountable for the crimes they commit. That's generally considered a good thing across political lines.
There's an expectation that the police will investigate regular crimes and bring the criminals to justice. For crimes committed by police, there's no such guarantee. Why is it wrong for a movement to focus on watching the watchmen?
In any case, what are protests and rallies going to do against gang violence? You need social programs to keep kids out of gangs, provide poor families additional assistance, improve living standards and so on.
