Attendance is optional, but highly recommended, taking into account the fact that many frontal lessons require, due to the very nature of the course, constant teacher/student interaction, called, for example, to examine photos, videos or other material extracted from 'investigation. The course is divided into 40 hours of lessons, including the carrying out of supplementary seminar activities, which will be held by Lt. Col. Cataldo Pantaleo, Commander of the CC Investigative Nucleus of Milan, with particular reference to crime scene examination techniques.
