Sorry, but this should absolutely unquestionably not be introduced. The implications for people being able to Facebook and Tweet pictures without knowing the passcode would be... very bad.
The point the original poster is making is that if the phone does NOT have a passcode set (or has one, but the timeout has not yet kicked in) then the quick-access camera slider should allow them to access their camera roll and its related operations.
Maybe as an option, otherwise I would share the same concerns as The Phazer.
No, you're still not understanding me. We're saying that if the device isn't locked with a passcode, then it doesn't matter if the quick-access camera allows you to post to Twitter/Facebook, because any person could just swipe-to-unlock and do it from the Home Screen anyway.
The point the original poster is making is that if the phone does NOT have a passcode set (or has one, but the timeout has not yet kicked in) then the quick-access camera slider should allow them to access their camera roll and its related operations.
The reason that this is bad is that it adds incentive for people to not use a passcode.
You don't want people saying "well, I would use a passcode, but then I lose all these cool features!"
Not that it's Apple's job to protect us, but I think it would be a mistake for them to willingly introduce items into the "con" list for when you make a pro/con list for "should I use a passcode?"
I see no reason why the Camera-from-lock-without-passcode shouldn't behave exactly the same as regular Camera. It should just be a shortcut to the Camera app!
