From there the cops get to use their imaginations.
Do they create a backdoor that allows them to get the data just after decryption from the end device?
Do they ask for this to happen in real time for all users and that firehose is directed at some gubment server?
Do they want the ability to unilaterally shut down the service?
Its a grab bag. If the cops are more creative than me, than we are in even worse strife.
