You just broke out. The sirens are close and the street is a long way down. Keep running.
Take off through the broken-down roof walls to stay on the escape route. Weave through the clutter: dodge past it, or press SPACE right in front of a low obstacle to vault it (run into one and you'll trip). Slide under ducts, jump into ledges to climb, and slide while airborne to roll as you land. S brakes. The cops follow your exact route, and some of them are waiting in the buildings next door.
