If one were to adopt the position that it is the responsibility of business to prevent fraud, well, you have a unique ability to do that that no other institution has. This is why I think your post is hypocrisy. Banks aren't lawyers, they don't know your clients like you do, and if you adopt the principle that "people should be responsible for the actions of their customers", you're going to have a significant amount of responsibility that nobody else can handle.
I was under the impression this is how it worked eg. that lawyers' only responsibility are to their client. Otherwise you would get some kind of weird conflict of interest in every case.
Well, it is the responsibility of HSBC to prevent criminal fraud by HSBC, which is one of the charges they plead guilty to in their plea bargain.
I don't receive any cash payments and I don't make any cash payments in my business. I am not a financial institution. This year, the value of the transactions that I participated in was probably around 100 million euro or so, and a fraction of a percent of this went through my account or ended up on my account, and all of it came from and went to banks. Not a cent was received in cash. Not a cent was paid out in cash. Now, HSBC and other banks probably have billions flowing through their system every second and in the order of millions received in cash or paid out in cash every second. I think it's natural to burden a few thousand banks with these rules, and not millions of small businesses.
