Sheriff Joe Arpaio of Arizona's Maricopa County is vowing to defy a federal order to halt immigration round-ups. On Oct. 16, Immigration and Customs Enforcement (ICE) told Arpaio to stop using the authority of the federal 287g program—which deputizes local law enforcement to help federal agents target undocumented immigrants—in his Phoenix street sweeps that have primarily led to arrests of people who haven't committed any serious crimes. Arpaio publicly refused as he headed a 12th major anti-immigration operation through the metro Phoenix county that day.

It has emerged that Pittsburgh police used an "audio cannon" dubbed the Long Range Acoustic Device (LRAD), manufactured by the San Diego-based American Technology Corporation (ATCO), against protesters at the G-20 Summit—the first time the device has been used on civilians in the US. "Yes, we sold one LRAD unit to a government agency—I don't know which one—which was used in Pittsburgh," said an ATC sales representative. (Daily Finance, Sept. 25) The LRAD has also recently been used against protesters in Honduras.

The American Civil Liberties Union is offering to help University of Pittsburgh students who were arrested during the Group of 20 economic summit in Pittsburgh—some of whom say they weren't even protesting. ACLU attorneys made the offer at a rally Oct. 1 attended by some 150. They say police conducted unlawful mass arrests and used excessive force.

Supermax prison: Obama's books objectionable
The federal government's most secure prison has determined that two books written by President Barack Obama contain material "potentially detrimental to national security" and rejected an inmate's request to read them.

In a joint press conference in Miami, several big-city police chiefs urged Congress July 2 to draft a new immigration policy that improves public safety by bringing the undocumented out of the shadows. Miami Police Chief John Timoney, Austin Chief Art Acevedo and former Sacramento Chief Art Venegas said local law enforcement has been undermined by the blurred line between crimes and civil violations of immigration law. Those who call undocumented immigrants "criminals" are misreading the law and hurting their own communities, they said. "When you remove the emotion from the debate," Chief Acevedo said, "no one can argue that it is in the best interest of public safety to keep these people living in the shadows." (NYT, July 1)

Last weekend, Shawna Forde, 41, leader of the Minuteman American Defense (MAD) group, and two of her associates were arrested in connection with the murder of a 9-year-old girl, Brisenia Flores, and her father, Raul, in Arivaca, Arizona. Local police are reporting that Forde and her posse broke into the Flores home dressed as law enforcement officers looking for money and drugs to finance her border-watch group—with the intention of leaving no witnesses behind.

A legal challenge in the US Supreme Court to the construction of the US-Mexico border wall was declared dead June 16. The justices declined to hear an appeal by the County of El Paso, Texas, to an earlier decision by a US federal court judge that allowed the Bush administration to proceed with construction of the controversial wall.

On a whirl-wind tour of the Southwest late last week, senior members of the Barack Obama administration laid out the White House strategy for border security, narcotics control and immigration reform. And contrary to the expectations of some border residents and advocates who were betting on a new approach last January, the new administration's strategic policy thrust mainly follows and even expands on the course long pursued by previous Democratic and Republican administrations. A solid alliance with the Calderón administration in Mexico City is a key component of the Obama border policy.
