This. For audio/photo/video delete removes it from view but does not delete until a configurable period of time has elapsed--and changing that configuration does not alter the timer on existing stuff. Also, no deletion can actually happen without contacting the associated account which can be set to deny the delete and can be set to upload anything queued for deletion. While this will not stop them from simply smashing the phone that's likely to carry far more consequences.
