Chen released a video in which he urged calm and indicated that neither his health nor the security of Taiwan were under threat. Within hours, police announced they were certain that the crime was not politically motivated, and that mainland China was not involved. On Internet chat rooms and talk radio, some Pan-Blue supporters theorized that the incident was faked in order for Chen to gain sympathy votes. These speculations were, however, considered highly offensive by Pan-Green supporters, and were not condoned by the Pan-Blue leadership until after Chen won the election.
