Does it make sense for Sick Boy's scam to be foiled so easily? SPOILERS

I'm talking about the one where he and Veronica set up rich men to be pegged by her, filmed and blackmailed for cash. Part of the purpose of a good blackmail scheme is to have some leverage (counter-leverage to the main, embarrassing leverage perhaps?) on the victim so they won't go running to the cops, or else some degree of separation from the likelihood of being caught. I assume the police busted him using the bank account details he gave to the victims to pay into after one of them made a complaint. Now, the Sick Boy of Irvine Welsh's literary universe DID often get his comeuppance when it came to scams or otherwise using people. But generally he proved very careful for schemes like these, instead usually being foiled by the betrayal of a friend. He would have used a degree of separation for sure. It makes sense for good business as a conman, after all. He would have set up the cash to go through a Cayman Islands or Swiss bank account to obfuscate the final destination of his bank account. Or used a fake name, or his dead grandmother's account. Or a combination. Whatever. But why didn't the cinematic Sick Boy cover his tracks better just like his literary counterpart? This also carries the implication that the EU "small business" funding scam they were performing would also get busted eventually, unless Renton has better banking savvy (as he very much did in the novel Porno) than Simon.
