What if "The Wire" had included a season on Immigration?

Via David Simon, one of the creators of The Wire:

Q: The police department, schools, industry, the media—these are all institutions that were addressed on The Wire. I’ve always wondered if there were a couple more institutions that would have been dealt with if there had a season 6, like the finance industry or health care, maybe?
A: Immigration was a theme that I would have done. The problem was that there was actually a delay of almost two years between season 3 and season 4. It took HBO awhile to renew the show. They were on the fence about it. By the time they did and we got back together and got into their schedule, it had been two years. For us to then stop and to retool and to do the research on immigration…

Q: Is there a large Latino population in Baltimore?
A: Just in the last decade. Baltimore had almost no Latino population when I was a reporter there, like minuscule. Then, suddenly, Central Americans began showing up in Southeast Baltimore. They’ve created an incredibly vibrant immigrant community.

Q: It would have been fascinating to see how The Wire would have treated this.
A: All you’ve got to do is watch the national debate and realize that immigration is this incredibly potent source of friction and ideology, and maybe always has been in American life. So I would have loved to have done that, but none of us knew Spanish and none of us had done any research on it. It would have taken us a little time, as it always did. But we had researched the school system and we were ready to do
that.
