The memo should be written to the head of local or Federal government agency advising them on a terrorism or homeland security issue.
The memo should be a minimum of 1 page and a maximum of 2 pages in length (written single space!).
As with any document you would provide a government agency, I expect a high standard in terms of the grammar and structure of your memo. The grade will less depend on whether I am convinced by your analytical judgment or recommendation, but rather, the grade will reflect how well you supported your key arguments and whether you convince me (the senior official addressed in the memo) that your objectively weighing the benefits and costs of the issue .
