It was decided that there was enough interest in bloodstain pattern analysis (BPA) to warrant the creation of the Scientific Working Group (SWG).
According to the guidelines for organizing a SWG, the Scientific Working Group on Bloodstain Pattern Analysis (SWGSTAIN) generated and ratified a set of bylaws in accordance to the Scientific Working Groups published in Forensic Science Communications (July 2002).
The experts come from various areas including law enforcement, federal, state and local laboratories, the private sector, and academia.
In 2004, the various sub-committees were discussing and drafting proposals in the following areas: SWGSTAIN meets twice a year at the FBI Academy in Quantico.
They have an American Society of Crime Laboratory Directors (ASCLD) representative.
