April 6, 2011 7:42PM # Surveillance, San Francisco-Style By [Jim Harper](https://www.cato.org/people/jim-harper) --- SHARE San Francisco’s [Entertainment Commission](http://www.sfgov2.org/index.aspx?page=335) will soon be considering a jaw-dropping attack on privacy and free assembly. Here are some of the [rules the Commission may adopt](http://www.sfgov2.org/index.aspx?page=2535) for any gathering of people expected to reach 100 or more: > 3\. All occupants of the premises shall be ID Scanned (including patrons, promoters, and performers, etc.). ID scanning data shall be maintained on a data storage system for no less than 15 days and shall be made available to local law enforcement upon request. > > > 4. High visibility cameras shall be located at each entrance and exit point of the premises. Said cameras shall maintain a recorded data base for no less than fifteen (15 days) and made available to local law enforcement upon request. Would you recognize a police state if you lived in one? How about a police city? The First Amendment right to peaceably assemble takes a big step back when your identity data and appearance are captured for law enforcement to use at whim simply because you showed up.
