In 1972, when the ATF separated from the Internal Revenue Service and became its own bureau within the Treasury Department, it had about 2,500 agents. At the time, the FBI had 8,700, the DEA 1,500 and the U.S. Marshals 1,900.Just seemed like an appropriate observance of the nomination of Andrew Traver as head JBT.
Thirty-eight years later, the FBI is up to 13,000, the DEA has more than tripled to 5,000, and there are 3,300 federal marshals.
The ATF, now a part of the Justice Department, remains at 2,500.
These folks would be happy to help you in your observance, I'm sure.
