In May, Warner was
for posting abusive comments to journalists on his Twitter account.
Vaughan, who played 82 Tests for England, 51 as skipper, before
retiring in 2009,
added: "In India a few months ago they would definitely have felt it couldn't get any worse and you come to England and it's a clean slate.
"People will say the management isn't strong enough but what does the management do when someone swings at an opposing player at 02:00 or 03:00?
"It's nothing that a coach or a captain can stop, it's down to that one individual acting in an irresponsible manner."
Asked if he felt Warner had "a short fuse", Bailey - who is skippering the side in the absence of the injured Michael Clarke - replied "not at all".
Bailey added: "I really enjoy playing cricket with him, love his enthusiasm around the group and wish I had the talent he has."
