Sysadmins understand encryption well enough to know there are plenty of different tools to use to encrypt data.<p>Allowing a backdoor to one tool does not grant access to every criminal communication.<p>Therefore, the request is pointless, it does nothing to make us more secure, and every IT guy knows it.  The sysadmin may not care about protecting others&#x27; privacy, but he knows this isn&#x27;t a good way to catch criminals because it won&#x27;t work.  The criminals will just use something else that the US government, or perhaps any government, cannot compel to add a backdoor.
