Is there any point in noting the circularity here? Probably not. I will, however, observe that the imprisonment of Afghani farmers and townsmen is also a political act, and in many or most of the cases (I doubt little that some of them may have committed militant acts) it is the American military that has thrust political importance into their lives. If some of them choose to react politically to being imprisoned unjustly for political reasons, I don't see what's to be surprised or indignant about. In fact, their suicides are only political because their imprisonment was political: convicted murderers (EDIT: or, more aptly, wrongly convicted murderers) who kill themselves in prison do not thereby commit political acts. Think about it.
