New Hampshire: Chinese Prostitution Ring Busted by Feds

Just now when I was tweeting about how everyone should be calling their members of Congress and Senators today (even the Dems!) to demand they fund the President’s wall, I noted that my top tweet of the last month was one about a Chinese sex trafficking ring operating in New Hampshire and Maine.
The poor young girls were brought to the US on tourist visas and literally held prisoner by their Chinese pimps.
From the New Hampshire Union Leader:

MANCHESTER — Two homes in the city — one in a middle-class neighborhood — were used as houses of prostitution in a sex trafficking ring that involved as many as two dozen Chinese women under the control of a Concord couple, federal prosecutors said Friday.

Neighbors of 87 Harrington Ave. — on a quiet residential street within earshot of Our Lady of the Cedars Church — said they had been complaining for two years about the operation. On Thursday, Manchester police and sheriff deputies used battering rams on the door and took away at least one Asian woman.
“Merry Christmas. For two years we’ve been waiting. Now our kids can come out and play,” said a woman who lived across the street who did not want to be identified.

….federal officials in Maine announced the indictment of a Concord couple and charged them with running the sex ring spanning Maine, New Hampshire and Vermont. Other sites of prostitution listed included hotels in Dover, Portsmouth and Kittery, where Portsmouth Naval Shipyard is located.
Multiple locations in the Portland, Maine area were also cited.
Sou Chao Li and Derong Maio, both 37, are each charged with one count of conspiracy to engage in interstate transportation and travel for prostitution; two counts of sex trafficking by fraud and coercion; and five counts of interstate transportation for prostitution. Li also is charged with possessing a victim’s passport as part of the sex trafficking scheme.

Neighbors of the Harrington Avenue home, nearly all of whom did not want to be identified, said they have been enduring traffic all hours of the day and night for years. They said middle-aged white men typically, many in SUVs and pickups, drive to the neighborhood, park on the street, enter the house and leave after 10 or 15 minutes. Some would wait in the car while another man was in the house.
“Sometimes they’d show up at my door,” one neighbor said. “I’d say ‘you guys looking for STDs? Go next door.’” [STD=Sexually Transmitted Diseases].

Here is what I want to know, did no one who reviews tourist visas from China notice any trend? We never hear about the details of that process. Was there fraud going on at the US Embassy in China?
