Absolutely. When I focused on that particular act and the 18 individuals, it was really to underscore the nature of the targeted sanctions that, as you say, try to be as precise as possible. As Professor Goldman notes, the idea is to try to avoid unintended consequences.
What has been the focus of that particular act underscores, it seems to me, the symbolic purpose that you focus on, which is essentially a shunning, essentially the sending of a message about these particular individuals and their particular roles in the death of Mr. Magnitsky in 2009.
From that point of view, the measure is a useful measure, but to the extent that considerable resources are devoted to the creation of these kinds of measures, it's not entirely clear to me that there is a larger policy purpose, other than the symbolic element of signalling and shunning that is served. From that point of view, it seems to me that these kinds of targeted sanctions tend to focus too purely on the symbolic side.
There's one other element, too, and it is that when you're talking about the Russian Federation, one of the important elements here is the ability of many individuals to sidestep and subvert these measures. There's also the element of basically being able to provide individuals with a certain benefit within Russian society of being the target of western sanctions.
