rules of conduct
announced by the the Seattle Parks Superintendent
earlier this year. One of the proposed rules advocated by
the Superintendent, but rejected by the Park Board was
"no spitting on park property."

I don't see anything that Reggie was doing that is
prohibited by these rules, however constitutionally-questionable,
vaguely worded, or difficult-to-enforce they might be.

The issue here is how to promote common courtesy and
respect in a public space. Reggie is a good friend of mine
and I have high respect for his integrity and courteous behavior.
He's not about to play loud obnoxious music right next to
your wedding ceremony in a public park. But if he did,
you might want to reconsider having your wedding in the park,
or he might want to consider fleeing the wrath of others in the park.
It's all a matter of common courteous concern for others, and
strict legislation of behavior does not seem to be the answer.
As I understand it, from talking to Reggie and reading his posts,
Reggie was acting in a responsible and courteous manner. But the rules
were unbending, strictly speaking unconstitutional, and the
punishment did not fit the supposed crime.

Cheers, S. in Seattle
where politeness is above average
