This week's cover story, "The Watcher," details the role Denver's Independent Monitor Richard Rosenthal has played in the ongoing controversy involving city law enforcement and alleged police brutality. It's a scandal that's made nationwide news and is shaping the mayoral race. How did the hullabaloo come about? Check out a timeline below of the major developments, along with video and photos of some of the controversial incidents in question.
July 2010: Ron Perea, former special agent in charge of the U.S. Secret Service's Los Angeles division, who'd helped run security during Denver's Democratic National Convention, becomes Denver's Manager of Safety, replacing retiring Safety Manager Al Lacabe.
July 9, 2010: Homeless street preacher Marvin Booker dies in jail in the new Van Cise-Simonet Detention Center.
August 11, 2010: Booker's family calls for video of the jailhouse incident to be released.
August 13, 2010: City pays out $20,000 to settle lawsuit filed by James Watkins, who claimed Denver police tech John Ruddy and Sergeant Randy Penn used excessive force and left him with facial lacerations and other injuries in a April 4, 2009 incident.
August 14, 2010: News breaks that Perea has chosen not to fire officers Devin Sparks and Randy Murr for the beating of Michael DeHerrera, 23, outside a LoDo nightclub on the same night Watkins says he was assaulted by the police, overriding Rosenthal's recommendation. Instead, Perea docked each of the officers three days' pay, even though a video of the altercation, captured by the DPD's High Activity Location Observation (HALO) surveillance system, shows the officers tackling DeHerrera, beating him with a sap and slamming his ankle in a car door after he'd apparently done nothing other than make a call on his cell phone:
August 16, 2010: Independent Monitor Richard Rosenthal and members of DeHerrera's family speak out about Perea's decision on Good Morning America, as the story spreads to CNN, Gawker and other national outlets.

August 20, 2010: Denver Police reopen the internal investigation into the DeHerrera incident, saying "new information has been made available."
August 21, 2010: Perea comes under fire for a second disciplinary decision, one involving a volunteer firefighter claiming that in November 2008, Officer Eric Sellers had put him in a chokehold, wrestled him to the ground, handcuffed him and screamed at him after the firefighter criticized the cop. Perea found that Sellers had lied during an investigation, but because the inquiry had taken so long, he didn't fire him, as the new disciplinary matrix indicated. Instead, Sellers was suspended for 45 days. "It had the potential of undermining all our reforms on force and lying," Rosenthal would later say.
August 23, 2010: Perea re-opens the internal investigation into the Sellers incident, then hands in his resignation, effective August 31. Deputy Manager of Safety Mary Malatesta will takes over until a new Manager can be found.

One of the officers was Randy Murr, who was also involved in the DeHerrera incident. Landau was eventually taken to Denver Health to be treated for a broken nose, lacerations and closed head injuries -- but not before he demanded somebody take photos of him:
