4. Why did Mayor William Alvord veto the Pigtail Ordinance?

The Pigtail Ordinance was an 1873 law intended to force prisoners in San Francisco, California to have their hair cut within an inch of the scalp. While the law did not discriminate between races, it affected Han Chinese prisoners in particular, as it meant they would have their queue, a waist-long, braided pigtail, cut off. The proposal passed by a narrow margin through the Board of Supervisors in 1873 but was not enacted until 1876.
