Good with me. The prison is about a mile and a half to the south of the plaza. It's not so much that one route is longer in terms of distance, but rather that going down the main road will take you straight there, whereas alleys will be close, erratically arranged (Tayibe's not the most organized), and cramped. The other course of action is to sneak through the houses, using alleys only when necessary-this will keep you from having to face an outright mob, but kicking down someone's door may provoke some aggression from the local inhabitants.
