I have been thinking about what a brief looks like for this kind of assignment. Not the surveillance theory — the logistical reality. Someone gave this man a location, a time window, a description of who to watch, and a cover that would make his presence unremarkable. The clipboard is not improvised. The uniform, such as it is, is not improvised. These things were prepared. Preparation means resources. Resources means a decision was made at a level above a single individual to commit time and material to watching this specific address.
