As I mentioned in a sibling post, that's a legal defense in the event such a drastic reaction occurs. Not a foolproof preventative measure to ensure it doesn't.
Involving your lawyer isn't a foolproof preventative measure either. But your lawyer having an established line of communication with their lawyers can get things cleared up a whole helluva lot faster than if you get booked, have no lawyer, and are having to find and get one up to speed only after you're sitting in jail.
The entire experience with Chase while I was assisting them was very positive, and they even mentioned something about putting me on their upcoming researcher leaderboard.
Since chase is a very big organization I would have to assume that another department took over the situation after, and decided to terminate my accounts to avoid any risk.
I will never know for certain as they have been very close lipped about the whole event.
I have had an unrelated similar problem with Chase before, local interaction was all positive in sorting out a cross border issue, about a week later someone from a different office closed the account without notification, information or recourse.
Local branch manager was frustrated but couldn't get any more information. The timing really made my life difficult for a few months, completely unnecessarily.
That was the last time I banked with Chase. A few colleagues told me they proactively left after also, due to the way it was handled - who knows if that was true.
I'm happy your experience (excepting the account closure) was positive! :)
I've got several Chase accounts myself, and glad to know they're not horribly hostile to such disclosures.
The original comment I replied to asked what difference it would have made in response to someone's "always involve a lawyer instead of trust these companies to do the right thing" post. Which is a generally good rule of thumb, as there's no guarantee someone else's experience would go as positively as yours did with Chase. So I wanted to point out a much more hostile outcome someone may feasibly experience in such a situation, to highlight the difference involving a lawyer could make.
