The video creator claimed that the video is only for re-enactment purposes and it is not 100% accurate. Perhaps it is only for the purpose of giving some light as to what supposed had happened and how the hostages was shot inside the bus.
The Manila Bus hostage animated video shows how Rolando Mendoza got angry and how he had used his machine gun which caused the lives of more than five hostages.
“Even though we need forensic evidence in order to simulate the possible occurrences during the crime this is just a recreation of what happened. It is not 100% accurate and does not intend to mislead people,” says the disclaimer on the video.
