More after the jump.

The U.S. Attorney's Office has dropped its investigation into Maricopa County Sheriff Joe Arpaio.

The Arizona Republic reports:

Scheel wrote that the agency declined to initiate any state criminal charges arising from its broader appointment to pursue state charges that may have come up in connection with the federal investigation. Several federal attorneys had been deputized to handle state crimes arising from the investigation.

"Law enforcement officials are rightfully afforded a wide swath of discretion in deciding how to conduct investigations and prosecutions," she wrote. "Unfortunately, such discretion can act as a double-edged sword: although it empowers fair-minded prosecutors and investigators to discharge their duties effectively, it also affords potential for abuse. Our limited role is to determine whether criminal charges are supportable. After careful review, we do not believe the allegations presented to us are prosecutable as crimes."

Ray Stern at Phoenix New Times is disappointed:

That's it.

Game over. No more wondering if the feds are going to haul Arpaio off for whatever crimes he may have committed.

Do we think a criminal case could have been made? You know it.

From arresting New Times executives at night under bogus pretenses to entering into an "unholy collaboration" with Andrew Thomas (who was disbarred for his unethical actions) to blatently targeting of political enemies to his "I was duped" remark about his former chief deputy's alleged crimes, Arpaio hasn't been held accountable by anyone.

Especially voters, who appear poised to re-elect him to a sixth term.

Nick R. Martin at Talking Points Memo notes:

Meanwhile, the Justice Department’s civil case against Arpaio continues. Earlier this year, the department’s Civil Rights Division sued the sheriff and his agency, alleging widespread abuse and profiling of Latinos. A department spokesperson told TPM late Friday that case was still ongoing.

This just in out of Phoenix, from the Associated Press:

Paul Babeu has been cleared in an investigation into whether he abused his authority as sheriff of Pinal County.

State Solicitor General Dave Cole said Friday that Babeu has committed no criminal violations and will not be charged in the case.

Babeu had asked the Attorney General's Office earlier this year to look into claims made by his former boyfriend, Jose Orozco, that Babeu threatened him with deportation.

Babeu also had accused Orozco of property and identity theft in his handling of Babeu's Twitter account and other websites. Cole cleared Orozco as well.

Cole oversaw the investigation to avoid the appearance of a conflict of interest on the part of Attorney General Tom Horne.

Maricopa County Sheriff Joe Arpaio has said something, uh, "interesting" again.

From Fox News Latino:

The sheriff of Arizona's Maricopa County, Joe Arpaio, said Wednesday in Tampa that the Obama administration should give him a "medal" for apprehending undocumented immigrants rather than investigating him for his methods.

"I should be getting a medal. The president should invite me to the White House ... and thank me for helping the government fight illegal immigration and the drug cartels," Arpaio told members of the foreign press covering the Republican National Convention.

Arpaio goes on to deride the Justice Department for investigating his office, and claims that Mexico should be making an effort to stem the tide of illegal immigration, saying, "It's a two-way street. It requires mutual cooperation."

But let's backtrack here. A medal for "fighting" drug cartels? Sure. Why not? While we're at it, we should give Arpaio medals for wasting his constituents' money in sending a deputy to Hawai'i to investigate the President's birth certificate.

Or perhaps one for ignoring sexual assault crimes within his jurisdiction? Maybe one for wasting and misusing $100 million in taxpayer money?

Arpaio may be making a name for himself worldwide for his antics (hey, remember the time he and Steven Seagal USED A TANK AND 40 DEPUTIES to knock down the wall of a suspected cockfighter?), but there's absolutely no way he should be celebrated by anyone—lord knows he does it enough on his own. More than that, there's no way he should have a job after this year.

Tonight on the Political Roundtable: Pima County Democratic Party chairman Jeff Rogers, Republican strategist Amilyn Gordon and Tucson City Councilman Steve Kozachik will talk about Flake vs. Carmona for U.S. Senate, Republican Jonathan Paton vs. Democrat Ann Kirkpatrick for U.S. Congress, Pima County Supervisor Ray Carroll's big win over GOP challenger Sean Collins, Ally Miller's win in the crowded GOP primary to replace Pima County Supervisor Ann Day (and the campaign-finance complaints related to Miller that were filed by two of her GOP opponents), Russell Pearce's loss in Mesa, state Sen. Frank Antenori's tough race this November against Democrat David Bradley, the latest in downtown revitalization politics and more.

Fangamer, based out of Tucson, deals in video-game-inspired apparel and accessories. After being open for business for the past four years, they've decided to reprint a number of beloved old designs, getting the money for that through a Kickstarter that will send shirts to folks for exactly as much as it costs to buy a shirt through the website.

Basically, they want you to invest in their company to get some shirts. Makes sense to me. But the heart of the matter is, their Kickstarter mission video is hilarious—5 minutes of your time well spent.

If you're interested in getting in on their Kickstarter, or just feel like buying some of their awesome-looking shirts and accessories, check out the links below.

Sergio Mendoza will bring an extra large band for Y la Orkesta’s performance Saturday at Hotel Congress. It’s an album release show for Mambo Mexicano!, the debut from Mendoza’s indie-mambo band.

Produced by Mendoza and Calexico’s Joey Burns, Mambo Mexicano! features contributions by a cast of more than 20 musicians. The album was recorded between November 2010 and January 2012, mostly at Wavelab Studio with engineering from Chris Schultz, Jack Sterbis and Craig Schumacher. Two tracks were produced at Waterworks Recording with Jim Waters.

Below, Mendoza describes the album, song by song, for the Tucson Weekly.

1. “Mambo Mexicano”
It’s probably the one that is the most mambo influenced. It’s one of the first songs that I wrote thinking in the Perez Prado style. It has Joey Burns, John Convertino and Jacob Valenzuela from Calexico, and Tom Hagerman from DeVotchKa playing violin. It features Salvador Duran on vocals and mambo yells.

2. “La Cucharita”
“La Cucharita” came in a week before I had to send the album off to Europe for the label to approve it to be out by April. We needed an extra song. We had been playing it live already, so we decided to record it at Waterworks with Jim Waters. I sing lead vocals on that one and we also have John Convertino playing drums and Joey Burns on guitars.

3. “Molino Rojo”
It’s a bar in Nogales, Sonora. This is like a 40-second segue. Even though it’s instrumental, it talks about what this bar would be, really mysterious. It’s painted yellow outside and I always wondered what it’s like inside. To this day I still don’t know what it’s like. It’s just one of those dive bars in Nogales, kind of like the place you don’t want to be in.

If you have unused or expired prescription medicine taking up space in your bathroom cabinet, don't pour them down the drain or flush them.

According to the Environmental Protection Agency, "Some medicines, vitamins and other supplements poured down the drain or flushed down the toilet may pass through wastewater treatment plants. They may enter lakes, rivers and streams which are often used as sources for community drinking water supplies. Water treatment plants are generally not equipped to routinely remove medicines and supplements."

This Saturday, Sept. 1, from 8 a.m. to noon, the Tucson/Pima County Household Hazardous Waste Program and the Pima County Sheriff's Department are sponsoring a medicine collection event at Eastside City Hall, 7575 E. Speedway Blvd. There's no charge to drop off materials. You can also drop off paint and other household chemicals. More info below:

In addition to old medications, you may also bring paint or other household chemicals for collection.
