Stock Market Crash of 1929
Attached is Q 1929 and it's all about Election Fraud and the word Firewall is used a lot.
From Investopedia:
Personal Finance Banking > Firewall
A firewall is a legal barrier preventing the transference of inside information and the performance of financial transactions between commercial and investment banks. Restrictions placed on collaborations between banks and brokerage firms under the Glass-Steagall Act of 1933 acted as a form of firewall. One purpose of a firewall is to ensure banks do not use regular depositors' money to fund highly speculative activities that could put the bank and depositors at risk.
