Is it possible to throw a camera attached to a rope within the event-horizon of a black hole and then pull it back in?
According to the observer holding the rope, the camera would never make it past the event horizon. It would appear to slow down to a standstill just above the horizon (though would effectively disappear because of redshift). At some point the rope would snap, but the camera would still not appear to cross the horizon. 

According to an observer with the camera, they would cross the horizon. But if they were lowered slowly, the rope would snap before they got there, since infinite force is needed to "hover" just above the event horizon. 

They would then find themselves inexorably falling inwards in the same way that you and I are inexorably drawn into the future and can't revisit the past.

That different observers in different frames have different versions of events is not unusual in relativity.
