Telephone tapping is officially, strictly controlled in many democratic countries to obey Article
12 in the Declaration of Human Rights " No one shall be subjected to arbitrary interference with his privacy, family, home or correspondence, nor to attacks upon his honour and reputation ."But still there's plenty of arguements about it.
Take Taiwan for example, in the past, government's despotism had allowed the agency to monitor people. The number of victims was increadibly high but unfortunately they were innocent in most cases. It made the progress of Taiwan slow down and the shortage of intellects. That's why lawmakers doubted on the Investigation Bureau's case of buying new devices to strengthen the phone tapping recently. Since that we are not a monocracy any more, why spend money on offensing people's privacy? On the other hand, the Bureau has the neccessary on attacking criminal and needs to renew their facilities. The most serious question is that this new device is mobile. With it, the agency could wire-tap on anyone only by parking a car nearby. It has already violated the law that cannot set a bug, video recorder, or other things which can monitor someone in private place. The Investigation Bureau needs to show the possibilities of criminal or destruction to the court to get the permission of wiretapping. But things could be change now. And it obviously offence our privacy.
Besides Taiwan, other countries are involved in it, too. However, some governments, like America, are still afraid of making promises not doing so. After reporters and officers accused CIA of telephone-tapping, they didn't even give a word on it. The prior chief of intelligence bureau in France had detected on president and his lover. Above showed our communication right is not safe anymore. How to make a good deal between people's privacy and the agency's work? The government needs to figure out.
