Why is it that Black lives only matter when killed by Cops?

Let's say you belong to some particular minority group, and within your group, tens of thousands die each and every year due to criminal gang violence. Since there is so much crime and Gang violence, Cops are constantly putting their lives in danger protecting law abiding citizens in your community.
Every year there are a few bad Cops who take law into their own hands, and kill a couple criminals.

I want you to be honest, and tell me if the thousands of lives, killed through crime and gang violence, matter. Are those lives as valuable as the few killed by the Police? If it were you, would you speak out on the thousands of deaths caused by criminal activity, or would you stay silent and only speak out on the couple lives killed by Cops? Does that makes sense to you? If your child was killed through Gang violence, would you protest in the streets, or just accept all the broken families and crime as normal daily life?

To not see through this Democrat Party's blatant political race bating strategy, is beyond ignorance. I believe it is what happens when a majority of Americans have chosen Government dependence over hard work and responsibility.
They are willing to ignore the silence from their Democrat Party when it comes to Black on Black murders, in order to continue the no fault social programs for able bodied people unwilling to work.

If your priority in life is making welfare a career, never getting ahead with real jobs created through a free market, a free market not regulated and taxed to death, then by all means vote Democrat. If on the other hand you want to live in neighborhoods where your child does not have to dodge bullets going to school each day, having a chance at getting a real job when grown, then vote for the Party trying to break the cycle of poverty. Vote for the Party not bent on securing your vote through Government dependence.

When Obama was President, record numbers of Black people on food stamps. Under Trump, record numbers of Black people with jobs! You choose the life you want for your children.
Democrats pander to voters with free stuff while Republicans give the choice of a real job verses Government dependence.
