This time Nick D'Arcy is guilty of not much more than stupidity.
He was guilty of assault four years ago and rightfully lost his place in the Australian Olympic team.
Posing in a photo brandishing legal high-powered guns is, as the Australian Olympic Committee says, foolish and inappropriate. But not much more.
It's a breach of the AOC's social media policy, but certainly not enough to warrant expulsion from another Olympic team.
D'Arcy and his mate Kenrick Monk have done their best recently to be left out of Australia's swimming team under the AOC's strict guidelines on bringing the sport into disrepute.
Monk has a prior for stupidity.
Last year he came close to a conviction for making a false statement to police when he claimed to have been the victim of a hit and run driver when he had actually broken his elbow by falling off his skateboard.
D'Arcy's character was also questioned last year when he declared himself bankrupt after being ordered by a court to pay former swimmer Simon Cowley $370,000 for leaving him with multiple facial injuries when he assaulted him in a Sydney bar in 2008.
Posing with some powerful weapons at a California rifle range is stupid, but not the worst thing the swimmers have done.
If lying to police or declaring yourself bankrupt to avoid paying a court ordered debt is not considered disreputable, then posing for a photo with some legal guns is hardly a major offence.
When the 24-year-old pair had finished three weeks of hard training and competing in California this week, they wanted some fun.
Firing some guns at a local rifle range was "fantastic", D'Arcy said, and posing for photos with the weapons was the idea of the facility's obliging owner.
Nothing they did was illegal, they didn't lie. They may have offended some people when the photos appeared on Facebook and Twitter. And for that they've apologised.
The AOC will wait for a Swimming Australia investigation before deciding whether the swimmers have breached their team agreement by acting in a way which "brings or would have the tendency to bring the athlete or the athlete's sport into disrepute or censure."
It's worth noting the story broke on the day Australia's Olympic shooting team was named.
A photo of six-time Olympian Russell Mark firing his gun was proudly displayed on the AOC website.
