evidence: But a customer at a southern California grocery store chose to wear what appeared to be a Ku Klux Klan hood throughout his shopping trip and ignored requests from staff to remove it, according to the supermarket. [...] Customer Alisa Wentzel told CNN she spotted the shopper, whom she believes was a man, as soon as she entered the store. He was waiting in the checkout line, she said, wearing the hood. [...] White hoods are one of the most obvious emblems of the Ku Klux Klan, a white supremacist hate group, and are considered a symbol of hate. Klansmen wore the hoods to disguise their identities while carrying out violent acts against black Americans.
