The stop of a moving vehicle driven by white folks is clearly a seizure within the meaning of the 4th Amendment. The legitimacy of a stop requires the government to prove that an officer had a reasonable and articulable suspicion that the motorist had been or was engaged in unlawful activity. To justify a particular official intrusion, 'the police officer must be able to point to specific and articulable facts which, taken together with rational inferences from those facts, reasonably warrant that intrusion. . . vehicles cannot be stopped in officers' unrestricted discretion; there must be at least reasonable suspicion that suspects have violated the law. [MORE] That is how the 4th Amendment works to protect white drivers when it is correctly applied by white judges, prosecutors and cops. To Blacks it is just a piece of paper. Here, stopping the car b/c the passenger had a wide nose similar to a robbery suspect is not a valid reason - such criteria could apply to milions of Black people (and maybe that is the point in a system of racism/white supremacy; we are all targeted suspects). 

From [HERE] and [HERE] In what appears to be police scanner audio, obtained by local NBC affiliate KARE, an officer can be heard racially profiling Philando Castile and his fiancé moments before they were pulled over by St. Anthony police in Minnesota.

The routine traffic stop, which was originally said to have been prompted by a busted tail light, ended with Castile’s death after police officer Jeronimo Yanez opened fire, shooting four bullets into the young man.

KARE verified that the license plate mentioned by police in the recording matches the plate of the car Castile was driving.  The location the officer gives also corresponds to the locations of the traffic stop.

“I’m going to stop a car,” the officer says on the recording. “I’m going to check IDs.  I have reason to pull it over.”

“The two occupants just look like people that were involved in a robbery,” the officer says. “The driver looks more like one of our suspects, just ‘cause of the wide set nose,” the officer continues.

A minute and a half later, the recording captures the first report that there was a shooting.
