Given the small amount of information we have it's possible to build up
a picture of events where the rider is an arse just as easily as one can
make a picture where the policeman is an arse.
I was picked up like this about thirty years ago, and got provoked into
being an arse myself. At least I did get a (long) anecdote out of it,
but I won't repeat it here.
