Everyone and their mother uses the app Snapchat. Everyone loves the little filters well there is a theory that every time you use the filter  it scans your face and sends your face to the FBI. The FBI has face recognition, and that the FBI went to snapchat and asked for them to do filters so that they can use the scans of the faces for whenever they need them. Just in case any snapchat users commits a crime the FBI can use the scans.
