How often will different law enforcement organizations use this kind of authority? How much cost and expense should individual companies be forced to incur supporting law enforcement by making software updates like this that spy on their customers. Is that something the courts are equipped to figure out?
Why I disagree with nearly everyone regarding Apple and the FBI.

Here we are trying to predict the future and create current policy, to solve this problem as if it is a solution for all future problems. The issue is not to create a law, it is to make a judgement based on the facts and accordance with the principles not write an investigative policy as the circumstances can and do change. If a court tried to be as prescriptive as you suggest, then it would be unable to come to a judgement.
