Shingle weavers and Everett,  Washington.  Sheriff deputies,  Pinkertons,  the lot,  opened fire when the strikers,  unionists,  started to walk off the ferry.  Many died,  and many more were wounded.   Or 1928 in Toledo, Oregon,  when a mob ran every Asian out of town,  because CD Johnson had hired Japanese green chain pullers.  A Swede wouldn't help the man next to him pull a board from a jammed up pile after the sash gang had dumped lumber on the chain.  Japanese would help each other.  That was more efficient and Johnson so noted and hired legal alien Japanese (US law forbade they become citizens but children born here were),  and even had a dedicated housing area for them (the new Port of Toledo  600 ton Italian travel lift paid for with Lottery dollars recently  occupied the site).  A mob threatened to kill every man, woman and child.  Let them flee town on the train.  Place now called Tokyo Slough.   The Japanese sued and won a settlement in Federal court in Portland.
