Governments should not undermine the effectiveness of legitimate technology.
No one government has the ability to demand that backdoors be put into reputable security software by every single vendor in the world. Moreover, even if they did, the simple truth is the bad guys will find an encryption or other tool they can use from some other, less reputable vendor (or create their own). The end result is the same: enormous additional risk and vulnerabilities to law abiding citizens, without meaningfully preventing the actions of the bad guys. Backdoors for some would mean backdoors for all, including repressive regimes, malicious insiders, foreign spies, and criminal hackers. Industry experts and non-experts alike with an awareness of the consequences have consistently warned that either outlawing encryption or introducing backdoors in security products will only cause criminals and terrorists to create and use proprietary forms of uncontrolled encryption, subjecting only the law abiding among us to eavesdropping or compromised security.
