There's certainly nothing wrong with getting involved with Warburg in the cum-ex scandal.
After all, the Hamburger Bank and its employees have now been convicted in three processes.
Even if not all judgments are final, the probable complaint against owner Christian Olearius is not an illogical step by the Cologne public prosecutor.
But one can also ask whether the investigators on the hunt for the biggest tax robbery in German history are really targeting the main perpetrators.
After all, there is much to suggest that the state banks under public law have turned a much larger wheel than Warburg with the opaque share group transactions.
The new black-green state government in Düsseldorf has just decided in the coalition agreement to clarify the role of the former West LB in the cum-ex scandal.
There are also demands in Hamburg that the parliamentary committee of inquiry into Warburg should also investigate HSH Nordbank's cum-ex deals.
Both are indeed urgently needed.
West LB in particular kept the financing going in NRW, the former heart of social democracy.
Today, NRW is liable for any possible tax debts.
