The law that says you can’t hypnotize anyone with a storefront display
City of Everett: Ord. 293-74
Hypnotists need to keep their hypnotizing inside where it belongs.
It is unlawful for any hypnotist or mesmerist, or other person, to exhibit or display, or permit to be exhibited or displayed, any subject of any hypnotist or mesmerist, or any person while under the influence of or alleged influence of hypnotism or mesmerism, in any window or public place outside of the hall or theater where such hypnotist or mesmerist is giving his entertainment or exhibition.
