But forget all that, let's talk about reality, let's talk about what could happen now, now that it is clear that not only is the SEC not extending these rules to other financials, as I had hoped, but is letting them expire.

Let's talk Downey Financial (NYSE: DSL) (Cramer's Take). Everyone knows this savings and loan is on life support. The headlines are just awful, the losses staggering, the deposits are running the wrong way, and it looks like another IndyMac is in the works.

Now, consider that more than 60% of the float of this bank is short, so it is virtually inconceivable you can get a borrow, so you shouldn't be able to short it, but naked shorting's allowed now, so you don't have to worry about a buy-in. Second, no upticks, so what's the point of waiting here?

You can only guess what the hedge funds will do now, right? The stock was down 25% yesterday. Why not just mash the stock to zero, the way IndyMac's was? I think that will happen today and tomorrow and Friday. By that point, the depositors will freak out -- I don't think they hedge funds will hire actors to stand in line, but there sure are enough of them unemployed in L.A. that it wouldn't be too hard to get 'em to hang out at 5 a.m. Just provide them coffee. (I wonder if the union would get angry?)

Anyway, with naked shorting and no upticking, the prospect of pinning Downey at 20 cents or 30 cents seems pretty likely to me.

Then the bank has to be seized. When it does, the FDIC's pressure hoard of insurance capital disappears quickly: Remember, it doesn't have any IndyMac takers yet because there is no mortgage resolution trust to dump bad loans to.

And voila, three days after the rules go away we have a bank panic all over again.

That's what I think will happen now. It just seems so obvious to me -- how can it not seem obvious to the SEC or the FDIC? Is it because, like the Ben Bernanke Fed, there are only academics and laissez-faire theoreticians running the joint with a handful of pols mixed in? Do you think they even know how the operation against Downey is going to work? Do they even know about this stuff?

I don't even think so or they would have extended the rule and broadened it.

I have seen the power of the rules in their ability to save even the worst of institutions that could be saved.

When the rubber hit the road in 1990 and I was shorting all of those failing bank stocks, the one thing that kept nagging at me was whether I could get a "borrow" on some of the worst ones, because everyone else was shorting them, too. In Confessions of a Street Addict, I documented how I got crushed on a Rutherford Savings Bank short I had when my broker could not find any more stock to lend me so I could stay short. I got bought in at a ludicrous price -- the broker just came in and bought the stock back well above the market -- and my quarter was almost lost.

That would never happen now, ever. Because the SEC doesn't care. Why? I don't know. My friend Mario Gabelli told me yesterday that he thought it was just because the academics sold them a book of goods that this stuff didn't matter. He could be very right. I think they are just over their heads.

I thought they may have figured all of this out after the July 15 bottom, but it turns out they really didn't understand that a return to the rules the way they were for 70 years was a good idea, as opposed to the laissez-faire garbage they believe in now.

Downey could have been Rutherford. It could have had a chance.

But not with this market. Not with this SEC.

Look out for this. It's Saturday's headline.

Be ready for it.

Oh, and I forgot something else: There are four or five Downeys out there right now that we all know about.

They will probably all meet the same fate in the same time frame now that the geniuses at the SEC have said all is well and good and the problems have gone away.
