Dallas cop killing

Blacks get killed all the time by cops so should blacks be happy that the five cops got killed? I don’t know it’s funny how the shoe could be on the other foot so fast. But blacks should just peacefully protest don’t get upset that a black man was killed in his car reaching for his permit for his gun to show this crazy cop that decided to shoot him in front of a child. So that child will never be right but is anyone upset about that of a black child in the USA that went through this trama I have children so I feel for this child. But do the USA no they worried about some cops life that singed up for this job. So let’s save the youth and tell the truth.
