in 2015, there were 1534 shootings by white cops against unarmed black people. Majority of these were in poorer areas of the USA.
Do you think it is blind Racism by whites against blacks? or...
Do you think that these white police officers see the upbringing of african-americans in these poor areas and know they are all struggling to make ends meet. Therefore making their actions unpredictable when attemping to pull them over or talk etc.
This ultimately leads to a scared police officer who has a gun and any slight action from the unarmed african-american is going to send them into a fight or flight mode in which they obviously use the gun against that unarmed person.
