Minkowski geometry preserves causality, that is all observers agree on the order of events, not necessarily on the time between events. So every observer sees me catching the ball after he sees me throwing it into the air. If I would move faster than light speed towards an observer, then he would first see me catching the ball and then throwing the ball. ( Since I traveled faster than the signal that the ball was thrown.)<p>So these claims, you could escape a black hole if you travel faster than light speed, should be read as, if we use our Euclidean sensibilities in a Minkowski setting,... It is in some technical sense correct, but without the technical details meaningless.
