Tijuana seems to me almost like New York where not that many people pay attention to pedestrian red lights? However, they do watch for traffic, and fast on coming cars, because if you don't you could get seriously hurt, as Tijuana drivers can be crazy.
A few guys have written that when they cross the street between Adelitas and Bar Tropical that a few of that cops stopped them for jaywalking, and then ended up hitting them up for a bribe on unrelated charges. I don't know if that's true or not? But just in case I never jay walk across that street in front of a cop, but rather go to the corner to cross unless I'm in a hurry and then I don't care.
