An as-yet-unidentified white man was captured on video hassling a black family about whether or not they showered before entering a hotel swimming pool in California, saying he was worried about “diseases.”

“Google it! Google the diseases in pools!” the man said at one point in the video.

When a hotel manager stepped in to mediate between Carle Wheeler, who was using the pool with her daughter before the run-in, he let the white guest go without identifying himself or questioning him further.
