The owners started displaying BLM signs during the George Floyd movement. But, on Wednesday, the owners found that someone had covered the signs with blue paint. A “thin blue line” flag was also stapled to their building.

“When they start painting the windows, the next thing to do is to firebomb it,” Samuel Thompson said.
