It's not JUST Starbucks at fault here. It's the institutional racism/bigotry that has the default setting for seeing brown/black people as fear or distrust.

Closing down that one Starbucks (which will likely happen b/c of boycotts) isn't going to change the larger picture. Those people lose their jobs and the corporation keeps on keeping on.

It's that people distrust and fear people of colour to this degree, that just sitting is a fucking crime.
