Macau watchers doubt there will be a return to further violence. They note that while Wan was in prison, the junket industry has cleaned up its act and become more professional. There's much more money at stake now and few want to jeopardize that.
"I just don't see these guys having the same sort of appetite for violence as they had in the past," said Aaron Fischer, a gambling analyst at CLSA Asia Pacific Markets. "In simple terms I think a lot of these guys have grown up."
Beijing is also anxious to maintain law and order in Macau, said Grant Govertsen, a Macau-based analyst at Union Gaming Group.
The measures taken by authorities ahead of Wan's release, Govertsen said, are "likely part of an effort to emphasize China's priority to keep Macau safe and prosperous."
