It's so they can find other infractions, like smoking marijuana
Not the broken taillight. It wasn't.
Not the "robbery suspect." All black men match.
Philando Castile was pulled over 52 times because police target black men with hostile situations that could get escalated to searches and small-time drug busts.
The answer is to end the Drug War and to repeal the "junk" infractions that enable police to initiate contact with minorities for no good reason.
As was said ad infinitum when I was learning to drive - it's a privilege and not a right.
Also seems to assume license testing is standardized with rigorous instruction regarding safety.
Some states don't require anything more than successfully completing a multiple choice test about signals and signs many folks end up ignoring anyway, and a brief on road exam.
People go in and drive safely for the 20 mins their subjected to a road test and sink into bad habits all the time.
I personally saw a wobbly 75 year old man with shakey hands (he updated his signature wearing coke bottle thick glasses) and a cane get his license renewal rubber stamped
Feeling safer already.
