infiltrate

違法薬物（合成麻薬）で息子を失った父親がみずから密売組織に潜り込み、組織の正体を暴きだした、というまるで映画のような話です。


An Australian man whose son died after taking a synthetic drug has gone undercover and travelled to China to infiltrate the crime gangs which have been exporting the narcotics.

Rod Bridge presented himself as a potential buyer and met with drug bosses in the city of Hefei to discuss importing supplies into Australia and was offered more than five types of synthetic drugs, including up to 200 kilograms of one drug. The bosses said they could guarantee delivery within seven days.

“We have lots of experience sending packages to Australia,” one seller claimed.

“We know how customs works. Don’t worry, Australia is safe.”

Mr Bridge was accompanied by a Channel Nine television crew and filmed the exchanges using hidden recording devices.

いわゆるスパイ、潜入捜査、と呼ばれるものですが、ここで使われている単語は、


infiltrate


です。

しみ込む、浸潤する、という意味ですが、軍事用語として潜入行動という意味があります。

軍事用語としての"infiltrate"は比較的新しいもので、1934年頃から見られるそうです。
