Sonny Bill Williams made an on-the-spot decision in unique circumstances when he gave his Rugby World Cup medal away on Sunday.
The decision has attracted praise and criticism.
Bear in mind that SBW was acting, perhaps not in the heat of the moment, but certainly in an emotionally charged moment.
SBW's medal went to 14-year-old Charlie Line who broke the Twickenham rules and jumped a security barrier and ran towards SBW as players walked around the stadium.
A security guard did what he was paid to do and tackled Charlie. The guard didn't have time to make a discretionary decision about how to deal with Charlie - he did the right thing, even if it looks a little harsh on video. He responded quickly to a security breach and a potential threat.
