Une loi devrait obliger les banques à démontrer qu'elles ont bien formé le personnel—relativement à tel, tel et tel aspect—afin d'éviter les abus, et que des mécanismes précis sont en place, sans quoi elles seraient présumées coupables.
Maybe if there was specific legislation in place that the bank had to show that they had properly trained their staff—they had to show this, this, and this—to prevent the abuses, and there also had to be other things in place, and if the bank hadn't done this, they'd then be presumed guilty.
