A coffee shop in Oakland is stirring controversy with its policy of "asking police to leave for the physical and emotional safety" of its customers and staff.

The owners of Hasta Muerte Coffee in the city's Fruitvale neighborhood posted their policy regarding police officers on Instagram in mid-February. The message first drew online protests, then became the target of demonstrations by Trump supporters on Sunday.

Protesters carried American flags and chanted slogans like, “Blue Lives Matter,” according to the East Bay Times. That slogan is often used to counter the Black Lives Matter movement against police abuse of black and brown people. Counter-protesters supporting the cafe turned up with signs and shouted, “Let’s go Oakland!”

Protest organizer Lindsay Grathwohl, 39, of San Lorenzo told KTVU, "We support police officers, and we think a boycott isn't cool."
