Most of the people I deal with would be regarded as unreliable witnesses. I've had front page splashes from crack addicts. A story I did about a footballer's father who was running a crack den in Nottingham, that came from a crack addict who even stole my tape recorder. We deal with unreliable people all the time but it's information that's important, that we vet and check thoroughly. So it can't be said that because Gashi had been described as unreliable by police that we thought he was unreliable.
