This one-day course can be considered a 2nd. part of the Firearms & Ballistics course. In recent years, criminal investigations have increasingly involved new types of weapons and devices, including ghost guns, conversion devices, and improvised explosive devices. Many of these cases involve new technologies, such as 3D printing, online distribution of parts, and homemade manufacturing methods. As a result, interpreters may encounter terminology that was not commonly heard in courtrooms just a decade ago. The purpose of this course is to help interpreters become more comfortable with this terminology so that when these topics appear in court, the explanations are easier to follow and interpret accurately.
