I worked in corporate trust, and then trust operations for twelve years.
DTC (as it was known then) is the custodian for all book entry (electronic) stocks and bonds.
True, they have records of EVERYTHING, but if you know what "street names" are, (and I'm not talking P-Diddy and J-Lo here), then you know that getting any useful information from their records would be next to impossible.
You'd have to get in touch with the financial institution(s) holding those stocks and bonds under "street names" to find out how much of a given holding is owned by whom.
I do not disagree with you at all. You know more than I about it I am sure. What I am suggesting is to come at it from a different direction. Trace it up from the companies that CLEARLY got nailed by the Naked Short Siders illegally. Through the day time and VOLUME of the stock traded, correlating that data with transactions recorded by DTCC should eventually show a pattern, its just correlating data. Its should lead to the Hedge Funds that have been doing this to such ruin. Just through the sheer number of times those Hedge funds line up with huge volumes done on Companies like... overstock.com
Bingo. You can find who was doing what. IF you can get the DTCC records. The FULL records. Good coders mine data like this frequently. Its more than possible to do, its possible to do it today. If you can get the records.
