On a daily basis, law enforcement officers come in contact with members of extremist groups. Most of the time, these encounters are ended without incident. However, when an extremist chooses to create a conflict with law enforcement, it can lead to violence, serious injury, and in some cases, death to the officer. In some cases, the extremists encountered by law enforcement may be bent upon committing acts of domestic terrorism. This course will discuss the correlation between extremism and domestic terrorism and what dangers are present for law enforcement officers each time they deal with a member of an extremist group. Additionally, identification of members of an extremist group as well as how to diffuse potentially violent confrontations with them will also be presented.
