Coffee Break Training: Fire/Arson and Explosion Investigation Curriculum: Use of Social Media in Arson Investigations [open pdf - 195KB]
"Social network services such as Facebook, Twitter and YouTube are increasingly being used in legal and criminal investigations. These services and others contain myriad potential leads and evidence that can be used by investigators to help identify suspects and successfully solve and prosecute arson cases. For example, it is estimated that there are approximately 3 million emails sent every second, 20 hours of video uploaded to YouTube every minute and 50 million tweets sent every day via Twitter. According to a study conducted by the International Association of Chiefs of Police in September 2011, approximately 88 percent of agencies surveyed indicated that they use social media; over 70 percent use social media for investigations and 58 percent of agencies not currently using social media are considering its adoption. Social media is a valuable investigative tool when seeking evidence or information about individuals or cases."
