The State and the defence have locked horns over the constitutional right of the accused not to incriminate themselves, in a landmark rhino horn smuggling trial involving Chinese nationals, whose families are reportedly blissfully unaware of their legal troubles in Namibia. Li Xiaoliang, Li Zhibing, Pu Xuexin and Wang Hui appeared yesterday in the Windhoek Regional Court in Katutura. They have been arrested for trying to smuggle 14 rhino horns worth more than N$2.3 million and a leopard skin of N$50 000 out of Namibia last year.
