There were at least two Hong Kong companies with booths to market fingerprint identification kits which were prominently marked as having been made in the US by American companies.
And (surprise, surprise ! ), all this was happening despite the US Congress having passed a law, which is still effective but only on paper I suppose, banning "the export to the People's Republic of China of any crime control or detection instruments or equipment" after the Tiananmen Square killings of 1989.
And some of our Chinese bootlickers on this Discussion Board don't want us to buy any thing from the US !!!
