Actually the Downtown Ordinances of 1994 destroy the Voluntary Guidelines (by banning playing in front of buildings and in front of street cafes). The Guidelines have continued because (after massive street protests against the Sitting Ban in 1994) police chose to use other enforcement mechanisms.

Bobby is correct in noting that Dan White (and City Council) ignored those enforcement mechanisms, which include laws against excessive noise, disturbing the peace, trespass, and (hard to believe but actually used) "terrorist threats" (used against Skidmark Bob Duran for his song "Shoplifting at the Bookshop Santa Cruz).

The point some of us made in 1994 and in 2002 is that enforcement mechanisms already exist. The police are just looking for broader powers, as ever. And it's not a wise thing to give it to them, nor does it address any real problems the merchants and street performers may occasionally have with each other.
