Source: FBI Investigators probing the violent storming of the U.S. Capitol by a mob on Wednesday have been seeking images and help in identifying suspects. The FBI, which is leading the investigation, has a range of investigative tools and technologies to help, including facial recognition software. Potential evidence abounds, thanks in no small part to self-surveillance - namely, many members of the mob livestreamed their breach of the Capitol, took copious photographs or posted images or intentions on social media. “Some people were being very blatant and flippant about it, smiling for the camera - those people are going to be very easy to find,” Doug Kouns, a retired FBI special agent and founder of the Indiana-based private-investigation firm Veracity IIR, tells The Washington Post.
