If the police have possession of the phone and have evidence that it may contain vital information then yes, they should have access.

However, I'm completely against the access of private information as a precaution, pre-emptive measure or for any other reason other than the one listed above. Sacrificing our privacy and freedoms for a false sense of security is cowardly and an insult to the people who have died to protect our freedoms.
