"The mounting tensions and suspicions between the two sides have only gotten worse with the introduction of military equipment and technology that has further separated communities from police – the most famous example being the extraordinary images of police dressed like an occupying army in Ferguson following riots sparked by the death of an unarmed black man, shot by a white policeman with seemingly little justification."
You might want to review all the footage available and even possibly listen to the recantations of the witnesses who originally claimed MB was just strolling along the street.
Contrary to the message being spewed by most media outlets, MB was not an angelic pillar of the community out to get groceries for his disabled neighbor. He was a thug running from a robbery and there were reports (later proven to be inaccurate) that he was armed during the robbery. He had a long and violent history with numerous contacts with the police.
That being said, everyone involved went way overboard with their reactions. From the police on the ground to BLM to our elected leaders there was hyperbolic messaging galore. Everyone involved carries some guilt for the aftershocks of MB's death.
BTW, I am a staunch opponent of this movement to militarize the police. We (the US anyway) have specific laws about that that are being run roughshod over.
