If the court approves, they can just go and obtain the computers. That is already solved.
They want to listen in, not shut the conversation down so storming in anywhere armed with your court order is not a solution.
So many people here are ranting on about this but what he said is actually 100% reasonable in that he stipulated the government needing a court order. The truth is that if they can stand in front of a judge and convince him you are a legitimate target then you have very little expectation of privacy. Based on that judges say so they can legally sneak in to your home and plant listening equipment if they have information that indicates they have a chance of recording you discussing engaging in illegal activities.
A few years ago things were much simpler for them, they could ask a judge nicely and he could order a tap your phone line. Nowadays though, that does not help them as much as it used to. They can take that warrant to your ISP, get full access to all your email, and still be none the wiser about what you are discussing if you have decent encryption.
If some could come up with a perfect solution to this problem where a judge could order something decrypted and only then could government use their magic key to access it then I personally would have no problem with it, providing a few other safeguards were also in place, such as full disclosure in the case that nothing is found after 6 months or a year or something. Obviously, this magic key would also have to be bulletproof so that there was no possible other way that government or anyone else could decrypt it.
The problem is that this perfect solution is is not what government goes looking for, instead they always seem to look for something that provides us no safeguards whatsoever. So even if it is possible (which I personally doubt anyway), there is sod all chance of them ever coming up with it and if anyone else does I can seem them actually supporting it.
