oh piss off. (you'll have grasped that, no doubt).
i think it's most unlikely that the father of a murdered man is wanting to send the message that his son was a criminal.
that does not preclude his son being a criminal, of course, indeed the manner of his death suggests that he knew some very unsavoury characters.
but you cannot infer that from the father's statement alone, nor should you, as his father was more likely to be trying to intimate the opposite, that his son was not a wrong 'un. here is his quote in full, seems to me to be very fond indeed.
"The victim's father, retired firefighter Roger Stevenson, 54, described his son as a "loveable rogue".
Mr Stevenson told the Sutton Guardian: "He was loved by lots of people. He was a very popular man, he was everybody's friend. He was always laughing."
