Blocked persons and letters of marque

Blocked persons and letters of marque

Jul 2022

Article I, Section 8, Clause 11 of the US Constitution reads:

The Congress shall have Power to declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water;

What are these Letters of Marque and Reprisal?

Essentially: Permission for private citizens to carry out acts of war. If you could convince the government to write one for you, then you were a “privateer” and you could go searching the seas for plunder.

The last time these letters were used was during the War of 1812 wherein the Prince de Neufchatel—that’s an American Ship, not a French vampire—was authorized to hunt British vessels. The last time they were considered was during Andrew Jackson’s administration of 1829-1837.

Surprisingly enough, this practice led to abuses, like people getting letters from the governments on both sides in a war, or pirates bribing corrupt governments to give their activities a veneer of legitimacy. Thus, the practice was mostly banned by the Paris Declaration of 1856.

The US refused to sign that declaration on the grounds that it had a puny formal navy. This position caused some difficulty during the Civil War of 1861-1865. While the Union had around 42 warships at the time, the Confederacy had almost none. Thus, the Confederacy turned to letters of marque, which disrupted Union shipping in the Caribbean.

This put Lincoln in a difficult position: He could have issued his own letters, but this would have angered Britain, which Lincoln hoped to get help from. He tried to belatedly join the Paris Declaration, but Europe felt that this was tantamount to taking a side in the conflict. In the end, the Union had to abstain from using letters of marque while the Confederacy did use them.

Legally, the Union did not regard the Confederacy as a legitimate party in a war. Thus, they tried captured privateers as ordinary pirates, under the theory that Confederate letters of marque were meaningless. This would have subjected those privateers to the death penalty. After Confederate President Jefferson Davis promised to execute captured Union officers in response, the Union backtracked.

To this day, the US has not formally agreed to the declaration, though it announced after the war that it would abide by it. So though it could in theory bring letters of marque back and this would in theory not violate any treaties, it would in practice be a big break with tradition and some people claim it would violate international law (if you believe international law exists).

Anyway, with 11 aircraft carriers, 72 destroyers, 22 cruisers, 22 littoral combat ships, 49 attack submarines, 14 ballistic missile submarines, etc., I’m thinking that the original motivation for using privateers doesn’t apply these days.

That being said, Rep. Gooden has proposed a bill that would allow the president to issue letters of marque to people who could then go and seize the yachts, planes, or other assets of any Russian citizen on the List of Specially Designated Nationals and Blocked Persons. That would be exciting.

Blocked persons

But hold on a second—there’s a List of Specially Designated Nationals and Blocked Persons? Yes, it’s maintained by the Department of Treasury’s Office of Foreign Assets Control. As I write this, it is 1,495,887 words long.

I wondered what was on this list, so I decided to check how often some different strings occur.


First, I checked how often the names of the most populous countries in the world occur, normalized by population size.

number of times different countries occur on blocked list

Apparently, USA ❤️ Japan which at 0.47 slightly beats India (0.55) and Ethiopia (0.56) for the fewest mentions per capita. (Edit: I corrected an earlier miscalculation due to a really embarrassing misspelling.)

Digital currencies

Next, I searched for Digital Currency Address - X for various values of X:

XBT bitcoin 349
ETH etherium 61
USDT tether 10
LTC litecoin 9
BCH bitcoin cash 8


Here are the counts of gender X for different values of X (There were no mentions of non-binary, etc.):

male 4854
female 466

Year of birth

I first got the counts for DOB year; for different values of year, but then realized that doesn’t work. To see why, here’s an entry from line 138357:

PUTIN, Vladimir (a.k.a. PUTIN, Vladimir Vladimirovich), Kremlin, Moscow, Russia; Novo-Ogaryevo, Moscow Region, Russia; Bocharov Ruchey, Sochi, Russia; Valdai, Novgorod Region, Russia; DOB 07 Oct 1952; POB Leningrad, Russia; nationality Russia; citizen Russia; Gender Male; President of the Russian Federation (individual) [RUSSIA-EO14024].

And here’s one from line 83844:

IZZ-AL-DIN, Hasan (a.k.a. SALWWAN, Samir; a.k.a. “GARBAYA, AHMED”; a.k.a. “SA-ID”), Lebanon; DOB 1963; POB Lebanon; citizen Lebanon; Additional Sanctions Information - Subject to Secondary Sanctions Pursuant to the Hizballah Financial Sanctions Regulations (individual) [SDGT].

Sometimes it’s the exact date and sometimes it’s just the year. How to get the counts for years in both of these formats? After a lot of trepidation, I remembered hearing about these things called regular expression and bash scripts and after a lot of terror and shrieking it’s “actually really easy”:

for i in {1910..2010}
    c=($(grep "DOB .\{0,7\}$i;" sdnlist.txt |  wc -l))
    echo $i, $c

Plotting those numbers, we get this graph:

number of people on the blocked list by birth year

Get to it, zoomers.
