How often do you cross Sampson? I go to TJ about every two weeks or so, usually on a weekday, and I come back at night, between 11PM and about 2AM when I go.
And I think we are mainly concerned about nights, as that's when the TJ cops shake downs usually happens. In the days the pedestrian lines are long, and there are many people, and we just don't hear about shakedowns during the days, but the nights are a different story.
Before there use to see between 3 and 5 TJ cops hanging around the taxi drop off point, and one time I seen as many as 10 TJ cops stopping mostly gringos asking them questions. I myself have never been stopped there, also many guys say they are never stopped, others say they are stopped all the time. ( with these guys I think the TJ cops can smell fear?)
Lately like I said the last 6 months or so, I see no TJ cops at night, and if I see any cops it's usually one who is just standing around, and doesn't appear to be shaking anybody down. Also there hasn't been any reports on these prostitution sties about shakedowns in that area, although there are a few in other places.
