The Church as Refuge?

I've been wondering a lot about the church's role in fighting human trafficking lately. Perhaps this stems out of my growing up as a Christian, or perhaps it stems out of the tremendous resources that are available in the church. During my time in San Francisco, I've walked the city's streets, down main roads and into alleyways, with the purpose of visually mapping out places of human trafficking. To the normal eye, they don't appear to be places of trafficking, but would likely just get named 'sleazy'. But inside the flashing neon lights of these massage parlors, hundreds of women are forced to work as sexual slaves in the city. There are a select number of parlors that I am keeping my eye on. One in particular has recently started using more provocative ads. I walked past this parlor today and noticed that its signboard had changed, another signal that something is happening. At night, this place appears shady and the small street it is located on is deserted. In the day time the street is filled with the usual tourist traffic. Today, I walked further down that road and found that there is a church on the opposite end of the road. A parlor on one corner, a church on the other? Polar opposites?
The church hasn't always been noted for taking a lead in fighting social injustice, but nevertheless I still believe the church has the potential to rise up into its place as a sanctuary of freedom. That is why I have been wondering how to bring the church into the fight against the crime of human trafficking. Because this is their chance to be a place of freedom, of refuge, and of transformational change. So as I discovered this church at the opposite end of the street, I wondered if they were aware of what happens just down the road, and if so what they were doing about it? If the girls were able to escape, would the church's door be the first place they would run to? Would the church members welcome them warmly or would they turn them away?
I'd love to walk through the doors of this church and connect them into the growing fight against trafficking. This issue is already personal to them because it is on their block!
