> the bank had lax controls in 2008 which allowed bad actors to move money through HSBC
Oh no! If only HSBC had the power to implement tighter controls that wouldn't allow it to receive boatloads of money. Oh well, it's not like they know a lot about money laundering, tax evasion, or handling large sums of money generally.
P.D. other comment mentioned that money flow attracts criminals, and I interpret it as criminals working on HSBC, not cartels using their services.
