Summary
"Past theories that have attributed sudden unexpected deaths following an altercation with law enforcement officers include positional asphyxia (M. D. Bell et al., 1992; Petty, 2004; Reay et al., 1992), neck restraints (Reay & Eisele, 1982), pepper spray (Granfield et al., 1994), and now conducted energy devices (Amnesty International, 1999). While police agencies have responded by altering restraint methods, such deaths continue to occur. ... The intent of this document is to assist in the systemic, consistent collection of evidence that may not last until the arrival of a formal investigation team."--Page 2.
