COPS: Third Dimension

It’s not easy cornering a timefugitive, so when you shout “We have you surrounded” you’d better block them in all directions as well as in the past and the future.
Also, pandimensional hyperbeings may not understand “Come out with your hands up.” Not only are you assuming they have hands, but in higher dimensions “up” is not always “un-down” and “out” may involve going further in and then wormholing back around.
Finally, “This is your last warning” is actually the first warning for retrotemporal outlaws. Those are the worst, since from their perspective they’ve only just gotten out of prison.
