Espionage..
 

From BBC news site

"A US defence department analyst has admitted giving classified information about military communication systems to a businessman working for China.

Gregg Bergersen, 51, pleaded guilty to a charge of conspiracy to disclose national defence information "to persons not entitled to receive it".

Mr Bergersen faces up to 10 years in prison when he is sentenced on 20 June.

Correspondents say his admission comes amid growing concern in Washington about the activities of Chinese spies.

Four others were arrested in separate case last month for allegedly passing secret details about the space shuttle and other US aerospace programmes to China."
