While I do sympathize with the plight of back people and latest police violence, I think that they are not helping the situation by engaging in violent protests that take even more lives and create a great deal of disturbance in USA! These protests ignite racial tensions but will not bring back the lives of innocent victims. What needs to be done here is clamping tight on the police force-punishing them appropriately and in the harshest of form if they take an innocent life or harass black people for no reason! They need to undergo training and psychological evaluation before being allowed to go out there and deal with criminals! They need to be psychologically stable and clear of racial bias, otherwise they are not suitable for this job!
