From October 1999 until October, 2001 Lawlor was commander of Joint Task Force-Civil Support, the first individual assigned to this position.[24][25] In this assignment Lawlor oversaw creation of the Civil Support Team concept, an initiative that enables the National Guard to play a greater role in responding to domestic terrorism than has historically been allowed since the passage of the Posse Comitatus Act.[26] Lawlor retired from the military in November, 2003.[27]
