The perpetrators of the shootings in Dallas are wrong and have done more harm than they can imagine. Killing police officers under the cover of a 'Black Lives Matter' march was inexcusable. However, the police in America have created an environment where any Black person must reasonably fear for their lives if stopped by the police. The escalation of police shootings of unarmed Black men combined with increased instances of Black people dying in custody hasn't yet led to any systemic change in law enforcement in America. If the establishment continues to disregard unjust killings and abuse of authority by the police then they are setting the scene for Black people to stand their ground and start fighting back.
I deplore the shooting of police officers in Dallas but my sympathies lie with the families of Alton Sterling, Philando Castille and the five hundred other Black people who have died at the hands of the police this year.
