The phenomenon that is racial profiling may be based in fear and prejudice, but it doesn't feel organic. Was there ever some incident where mass crimes were committed by angry mobs of blacks, against whites solely for their soft spoken good natured disposition? Looking to sink our teeth into their gullible, Jesus fearing hearts. Not to my recollection.
Here's where the seeds were planted. During slavery, blacks were no threat. Insubordination was severely punished. After slavery, to maintain a flow of cheap labor, laws were enacted, black specific laws. Things like, no farmer could sell his crops after dark, punishable by law, or if you couldn't prove you had a job, you go to jail, creating a new prison workforce and saving the tobacco and textile industries. The high number of black arrests combined with the lack of white arrests, for crimes against blacks, gave birth to the idea that blacks were not ready for freedom and were inherent criminals. These purposely force fed ideas, by Government to the people, to justify the treatment of blacks, became what defined newly freed blacks in America. And gave birth to segregation, and modern discrimination, prejudice and racial profiling.
The fact that this hasn't been addressed by a figure of white authority, on a national platform, gives some sense of legitimacy to an antiquated idea that's been passed down for two generations, adapting and evolving, it can be killed but that doesn't seem to be part of the plan.
