No it doesn't. A disposable cell phone like Tracfone, calling from another neighborhood though, that would work.
Are there any Mexicans in this crowd of people? Not be racist, but call INS and anonymously report possible illegal aliens living there. A couple years ago, like 15 migrant workers rented a small house across the street from a library in my town. About two weeks later, I happened to be driving by the house and saw two Border Patrol trucks and a couple of Mexicans in handcuffs. Next day, there was a For Rent sign up in the building.
I'm pretty sure he won't be able to tell the difference between a Mexican and a Puerto Rican.
