At 11 a.m. on a weekday, Calexico rehearses for its upcoming tour in a cramped studio on the south side of Tucson, Ariz. The stereotypical musician would just be getting up, but lead singer and songwriter Joey Burns has been up since dawn with his twin baby girls.

Trumpet player Jacob Valenzuela arrives late to the rehearsal — and that's because his washing machine broke and he had to deal with a small flood. Valenzuela grabs his trumpet as the band launches into "Splitter," the first single from Calexico's new album.

The United States' southern border bristles with technology and manpower designed to catch illegal immigrants and drug smugglers. Since 1986, the government has spent hundreds of billions of dollars on fences, aircraft, detention centers and agents.

But even as federal budgets shrink and illegal immigration ebbs, experts say that there's no end in sight for the growth of the border-industrial complex.

A Growing Investment On The Border

Young people brought to the U.S. illegally began applying for a deportation deferral and a two-year work permit on Wednesday. It's the boldest immigration program yet by the Obama administration — putting into effect elements of the so-called DREAM Act even though it has not passed Congress.

Lizbeth Mateo has high school and college diplomas from California and evidence that she has been in the country continuously for at least five years. What she wants now is assurance that she won't be deported.

If you're from a state once considered the "Old West," odds are you've heard of a Boot Hill graveyard. Turns out there are a number of Boot Hill cemeteries in the West, so named because many of their inhabitants died violently — with their boots on.

But of all the Boot Hill cemeteries, none is as famous as Boot Hill in Tombstone, Ariz.

It's a tough-looking place. No lawn, just gravel, mesquite trees and cactus. The graves are covered with stones to keep varmints from digging up the bones.

In Arizona, the man accused of shooting Gabrielle Giffords at a gathering of her constituents in Tucson last year will be in court today. Jared Loughner allegedly killed six people in that attack and wounded 13 others. He was declared mentally unfit to stand trial, but now that may change. As NPR's Ted Robbins reports, Loughner's lawyers are expected to offer a deal to help him avoid the death penalty.

Maricopa County, Arizona, Sheriff Joe Arpaio made a court appearance Tuesday and faced questioning. Arpaio is accused of racial profiling in a civil class-action lawsuit.

The self-proclaimed "Toughest Sheriff in America" is facing one of his toughest tests. A trial begins Thursday morning in Phoenix accusing Maricopa County Sheriff Joe Arpaio of violating the civil rights of Latino citizens and legal U.S. residents. The class-action civil suit says the sheriff went over the line in his efforts to crack down on illegal immigration.

It's all new for Achilles: his name, his horseshoes, the surroundings at his home near Nogales, Ariz.

"To break 'em from what they're focusing on, you want to turn 'em from one side to the next," Border Patrol agent Luis Navarro says as he carefully leads Achilles into a round training arena.

Navarro holds the mustang by a short lead, and teaches it commands to trot and to slow down.

It will be weeks — maybe longer — before the one part of Arizona's immigration law the Supreme Court left standing goes into effect. A lower court has to remove its injunction before local police are required to ask about immigration status. But as NPR's Ted Robbins reports, there's already been a backlash.

AUDIE CORNISH, HOST:

To the Supreme Court now and a much-anticipated decision on Arizona's controversial immigration law. The justices struck down most of SB1070, as the law is known. But the court did unanimously allow one key provision to take effect, and that's giving both sides reason to claim victory. We'll delve more deeply into the ruling with Nina Totenberg elsewhere in the program, but now to reaction from Arizona and NPR's Ted Robbins.

And Ted, let's start first with the three provisions of this law that were blocked. What were they?

Voters in Southern Arizona decided Tuesday who will replace former U.S. Rep. Gabrielle Giffords for the remainder of her term: her former district director, Ron Barber. Giffords resigned from Congress in January to focus on recovery from injuries she suffered in a shooting in early 2011. Barber was also injured. His Republican opponent, Tucson businessman Jesse Kelly, narrowly lost to Giffords two years ago.

Voters in southern Arizona's 8th Congressional District are deciding who will fill the seat formerly held by Rep. Gabrielle Giffords. The Democrat resigned in January, a year after she was badly injured by a gunman at a district event in Tucson.

Giffords' resignation set in motion a special election to serve out the rest of her two-year term. Giffords' former district director, Ron Barber, won the Democratic nomination uncontested. Jesse Kelly easily beat three opponents in the Republican primary.

The real estate market has turned around in some parts of the U.S., but many buyers aren't seeing true bargains anymore. Investors are driving up prices, and inventory is low, especially for homes priced under $250,000. That's not great news for anyone hoping to buy an affordable house to live in.

Arizona is home to one of the nation's extraordinary turnarounds. The Phoenix-area median home price rose 20 percent over the past year — 6 percent in March alone. And Tucson was recently named the nation's best market for investors. But the easy money has already been made.

If you're the kind of person who screams at the sight of an insect or spider — or worse, steps on it — then a new store in Tucson, Ariz., might not be the best place for you to pick up a new family pet.

Owner Ken "The Bug Guy" MacNeil says his store is the only retail pet shop in the country devoted to insects and other arthropods. Judging from the recent opening day crowd at the store, plenty of people think the critters make great pets.

SCOTT SIMON, HOST:

This is WEEKEND EDITION from NPR News. I'm Scott Simon. The Republican campaign for president literally heated up yesterday. Former Massachusetts Governor Mitt Romney, the likely nominee, was in the Phoenix area. He addressed a rally of sun-soaked supporters, a meeting of Republican state chairmen and a group of Hispanic leaders. Now, in the moment, we'll hear more about how Republicans plan to reach out to Hispanic voters this election season. First, NPR's Ted Robbins has this report.

MITT ROMNEY: Thank you, thank you.
