Turning a blind eye to money laundering especially when given chances to fix it, and given that money laundering is enabling criminal enterprise that fucks up everyones life, from a household name bank that used to be my high school bank (point is how they market themselves as a nice bank) well I don’t know what to say. Not a meme though.

It's a meme in the sense that it's propagated virally and the story has mutated as it goes. There's no evidence that HSBC were wilfully blind to anything.
