Cramped streets are dangerous when the enemy is stronger. After all, it is extremely difficult to escape, and sometimes it is simply not possible. It doesn't matter how law-abiding you are, as long as it's a matter of life and death. Jump right through the window, breaking glass and knocking out the shutters, and break into another part of the street right through someone else's house. The resident of the house will not be happy, but he is unlikely to have time to do anything if you immediately run out the door.
