Busy, busy. Cops getting arrested, cops pleading guilty, cops going to prison. And, of course, the ever-present drug-dealing prison guard. Let's get to it:

In Miami, three Boston police officers were arrested last Thursday after taking $35,000 to protect a cocaine shipment in an FBI sting operation. Ringleader Robert Pulido, 41, and fellow officers Carlos Pizarro, 36, and Nelson Carrasquillo, 35, traveled to Miami to celebrate their drug protection deal and plot more deals with undercover narcs they thought were cocaine traffickers, the Associated Press reported. Pulido allegedly got into a variety of criminal activities, with his junior partners sometimes joining in. Those offenses include protecting drug shipments, identity theft, sponsoring illegal after-hours parties with prostitutes, money laundering and insurance fraud, according to prosecutors. They are in jail awaiting an August 2 removal hearing.

In Deming, New Mexico, a Luna County Sheriff's Deputy was arrested Tuesday on methamphetamine possession charges after he took the dope off a man during a traffic stop, but never turned it in as evidence, the Luna County Sun-News reported. Deputy Tommy Salas, 33, turned himself in Tuesday afternoon and was release on $7,500 bail on one count of meth possession. Salas had been on paid administrative leave since June 9, when the sheriff's office and local prosecutors opened an investigation into "discrepancies" in the traffic case. Another officer at the scene had watched Salas take the drugs from the driver and heard him vow to turn them in, but it never happened.

In Lebanon, Ohio, a Warren County prison guard was arrested Monday for accepting drugs and money to be smuggled in to a prison inmate, Cincinnati's Fox19-TV reported. Corrections Officer Michael Miller, 37, went down after accepting marijuana and $600 from an undercover agent, capping what local police said was a three-month investigation. Miller is charged with two felony counts of conveyance of drugs and is in "mandatory incarceration" because he is a corrections officer.

In Laredo, Texas, a former drug task force deputy commander pleaded guilty last Friday to extortion charges for accepting tens of thousands of dollars from drug dealers to protect their operations. According to the Associated Press, Julio Alfonso Lopez, 45, accepted at least $44,500 from his middleman with the traffickers, Meliton Valadez, who has already been convicted for his role in the scheme. The pair were also accused of providing sensitive police information to traffickers and providing storage spots for cocaine shipments. Lopez pleaded guilty to a conspiracy charge.

In St. Louis, a former St. Louis police officer has been sentenced to nine years in prison for his role in a drug conspiracy, the Associated Press reported. Former officer Antoine Gordon was convicted in an April trial of checking police databases to see if people buying heroin from the drug ring leader were working as snitches for police. Gordon was one of 19 people who have pleaded guilty to drug or weapons charges in the case.
