So, ok. Please don't misunderstand. I think HPD should put their resources into serious crimes, and basically defund their "vice" squad or keep it to a minimal size. From a utilization of resources, $1 spent to try to solve a murder is better than $1 spent to bust a hooker or illegal poker den.
With that said, there's a group of HPD who's job it is to bust hookers. So, they can register on the same websites we use. They can see the same listings and phone numbers that we see. So...uh...just schedule an appointment, show up, and slap on the cuffs? What stops them? Sure, there's the "Basic plus 2" system. Can't they just arrest 2 girls, and have a female officer impersonate the hooker used as "reference" to bust the next one, using their seized phones?
Frankly, if you think about it, HPD must feel something similar to what we do. They do bust people, but it doesn't seem to be nearly the number that they are physically capable of arresting. It seems more like these occasional busts are sort of propaganda on behalf of HPD, where they find the seediest, shoddiest looking den of open hookers in Houston, and bust them, showing that they have "done something", "drugs on the table" style.
