The WSJ article was penned by former governor of Oklahoma and current American Bankers Association (ABA) President, Frank Keating. The ABA is a national trade association that represents all banks (source: http://www.opensecrets.org/news/2012/09/capital-eye-opener-s...), essentially a lobbying firm for the banking industry. One wonders why the banking industry would care enough to have the President of their lobbying firm publish a piece about this in the WSJ. Surely a Republican from Oklahoma cares little and less about the financial well being of porn stars.
On the same exact day the WSJ article was published (April 24, 2014), an article written by Jason Oxman, CEO of the Electronic Transactions Association (another lobbying group) was published, also lambasting OCP: http://thehill.com/blogs/congress-blog/economy-budget/204174...
These two articles, if you can call them that, given the authorship, are the only source pieces at the root of the current media interest in OCP.
It's clear (to me anyhow) that the porn stars aren't the story here, they're just the fodder to get the people in a tizzy about OCP. I'm wondering what else is in involved in Operation Choke Point that's making the banking industry and the payment processors call out the big guns. Whatever it is, I imagine large sums of money are involved.
