Though there is only a small chance that any given diplomat would actually have to pay the city for those parking tickets, the sheer number of tickets collected is staggering. Consider, though, that the diplomat's embassy is actually the front for many different diplomatic missions. Diplomats from a number of different countries may reside in the same buildings.
So, for example, the Swedish Embassy has a lot of parking tickets, not just for Sweden but for other countries with diplomatic missions there. The UK has over 200 embassy employees in NYC, and many of them reside in the US as diplomatic staff. The Embassy of Japan in the US has about 70 employees in NYC, and they, too, have a lot of parking tickets. So with over 3,000 diplomats in the US, there's a lot of reason to suspect that many of those diplomats have outstanding parking tickets. In fact, I can almost guarantee that as someone who has lived in the US for the past 15 years, many of those diplomats have outstanding parking tickets. The sheer number of diplomats makes the odds that someone has outstanding parking tickets almost astronomical. I'd say that the odds of any given diplomat having outstanding parking tickets is about 80%.
In the case of the United States, I found myself considering the number of parking tickets that have been issued to the diplomats of the United States around the world. The United States has over 3,000 diplomats worldwide. The United States employs over 100,000 people in Washington, D.C., so even at the best of times, the traffic in Washington is bound to be overwhelming. Because the US is the most geographically diverse of all the G8 member nations (excluding Canada), a lot of diplomats park in New York City. The United States has a whole lot of parking tickets to pay. The overall total is $12.6 million according to The New York City Department of Finance . (Also, I'm not sure what the correct internal rate of return on that is.)
An even better way to visualize this would be to imagine a model of the world that was populated with a single, global diplomat. This model would have an infinite number of parked cars, each of which would have a unique plate number.
Diplomats, visitors, and Americans all have an interest in ensuring that this historic moment passes as peacefully as possible. Recent history has taught us that raising the very real issue of human rights violations can be used against an individual, particularly if that person is a perceived enemy. 827ec27edc
