Australian author Corey Donaldson has been found guilty of using intimidation to rob a Wyoming bank of more than $US140,000.
In his closing address to the jury in the US District Court in Cheyenne, Wyoming, on Thursday, Donaldson, who represented himself, admitted he robbed the US Bank branch in Jackson Hole, Wyoming on New Year's Eve.
However, Donaldson asked the jury to find him not guilty because " it is the patriotic thing to do" and it was time to make a stand against banks.
His advice fell on deaf ears.
The jury took just 50 minutes to convict him.
Donaldson, 40, originally from Melbourne, faces up 20 years in a US federal prison.
He compared himself to Robin Hood and US civil rights champion Rosa Parks, telling the jurors he robbed the bank to give to the poor and make history.
To commit the robbery, he handed a note to the bank manager warning him Mexican drug cartel members were waiting outside, had placed military grade explosives in the snow around the bank and would hunt down and kill him if money was not handed over to Donaldson.
