Just some data points from a white guy,  
I have been followed around a store many times.  ( It has diminished as I've gotten older. )  I wonder how many white people know when they are being followed around a store.  There was a gal I used to see all the time in the FM on Division that was clearly store security who followed people around all the time and they were almost always white, and they were oblivious that she was doing it.  (She never followed me because she knew that I knew who she was.)
And while not a yearly occurrence, I have been pulled over a half dozen times in my life for no infraction.  Twice I've been pulled over for driving while white.  A couple times for driving while having a vehicle/appearance that didn't fit the  area. And a couple time for being out at odd hours.  
Also once with a friend ordered to the ground at gunpoint, cuffed and questioned because we matched the description of two armed robbery suspects.
