Yay, lets fine the victims...
Any fine paid by a company ends up being recovered via their customers, who in this case are also the victims. So, effectively, the FCA are fining the victims.
When the management of a company are held fiscally and legally responsible for the performance of their company, we'll see real change. Until then, we're just gonna see more of the same.
I'll sum it up like this - only a single banker was prosecuted after the crash. Just the one. And he wasn't even a high level executive.
