It can't show you a list of contacts.

You can however ask Siri to give you someone's specific contact information, which is definitely something Apple should fix.
Supposedly not that way, but perhaps the way described in one of the videos. And probably all by design essentially.

Yea you can say - show my contact. Then you get all your email addresses, phone numbers, Skype, FaceTime, home and business addresses, your connected relatives, kids , father, mother. The whole motherload.

Turning off siri stops it but ruins the siri experience. They should make a setting to show what you want. i.e. limited contact info when locked. Maybe thats too hard for the programers.
