INVESTIGATIVE TECHNIQUES LAW
Copyright 2001 - 2015  Edward S. Armstrong, Jr.

All law enforcement officers must confer with their training officers, legal advisors and prosecutors regarding the following legal issues. State law can be more restrictive (pro-defendant) than Federal law. Federal circuit courts of appeal often disagree with other Federal circuit courts on issues not yet decided by the United States Supreme Court. Also, lower courts (State and Federal) sometime disagree on what a Supreme Court decision means. The following statements are not to be taken as legal advice.
