They were used to assist or replace regular officers in high-crowd events, such as Memorial Day, and during the 1918 flu pandemic, worked for two weeks to enforce stringent health regulations.

The new Chicago Police Department Headquarters was opened on June 3, 2000, replacing an extremely aged and outdated building located at 1121 South State Street.

Working with Chicago-based Thresholds, an addiction recovery agency, the police give those suffering from substance abuse disorder one final chance: If they enter the program, charges against them are dropped.

The report strongly criticized the police for a culture of excessive violence, especially against minority suspects and the community, and said that there was insufficient and poor training and a lack of true oversight.

[45] This was in the wake of a 2017 Department of Justice report which found that the CPD had a history of civil rights violations by officers, including a "pattern and practice" of police brutality and abuse.

Time published an article stating: With billy clubs, tear gas and Mace, the blue-shirted, blue-helmeted cops violated the civil rights of countless innocent citizens and contravened every accepted code of professional police discipline.

The police even victimized a member of the British Parliament, Mrs. Anne Kerr, a vacationing Laborite who was maced outside the Conrad Hilton and hustled off to the lockup.

On December 4, 1969, Black Panther Party leaders Fred Hampton and Mark Clark were shot and killed by officers working for the Cook County state's attorney, Edward Hanrahan.

[48] Semen found at the scene and subsequent DNA tests totally cleared the boys of the crime and pointed to convicted sex offender Floyd Durr.

[49] In the summer of 1999, two unarmed black motorists, Robert Russ and LaTanya Haggerty, were fatally shot in separate incidents involving the Chicago Police.

The pursuit, labeled "high-speed", did not exceed 70 miles per hour, but Fyfe contends that the adrenaline rush of the chase, coupled with the officers' reliance in their numbers, led to their ignoring impulses to maintain rational thinking in a potentially non-deadly situation.

[54] In October 2001, Deputy Superintendent William Hanhardt pled guilty to running a nationwide jewel-theft ring that over twenty years may have stolen five million dollars' worth of diamonds and other gems.

[58] Since the early 1980s, official investigations have responded to numerous allegations against former Commander Jon Burge, who has been accused of abusing more than two-hundred mostly African-American men from 1972 to 1991 in order to coerce confessions to crimes.

In summer 2006, special prosecutors completing a four-year investigation concluded that they had enough evidence to prove crimes against Burge and others, but "regrettably" could not bring charges because the statute of limitations had passed.

[60] In October 2008, Patrick J. Fitzgerald, United States Attorney for the Northern District of Illinois, had Burge arrested on charges of obstruction of justice and perjury in relation to a civil suit regarding the torture allegations against him.

[7] On November 19, 2002, Rachelle Jackson, a registered nurse, was on her way to work when she witnessed a vehicle accident involving a patrol car, in which Officer Kelly Brogan was dazed and her partner was unconscious.

Fearing an explosion, Jackson removed both officers from the vehicle, and voluntarily went to the police station under the assumption of giving a statement after being informed that Brogan's service weapon was stolen.

[69] In 2007, security camera footage surfaced of an intoxicated off-duty police officer, Anthony Abbate, punching and kicking a female bartender, Karolina Obrycka.

[77] On November 13, 2012, a federal jury found that a "widespread code of silence" within the Chicago Police Department had allowed Abbate to feel that he could attack Obrycka without fear of reprisal.

On June 23, 2009, Abbate was sentenced to two years probation, including a curfew between 8:00 p.m. and 6:00 a.m., mandatory attendance at anger management classes, and 130 hours of community service.

Chicago Police Officers Jerome Finnigan, Keith Herrera, Carl Suchocki, and Thomas Sherry were indicted in September 2007 for robbery, kidnapping, home invasion, and other charges.

A Cook County judge dismissed all criminal charges accusing them of robbery and home invasion after some evidence was proven to be false, and witnesses in the case against Sherry and Suchocki were unable to place the officers at the scene of the crime.

Publicly available police video shows Sierra circle the prone Farmer as three bright flashes emit from approximately waist level.

On February 18, 2015, Spencer Ackerman, reporting in The Guardian, covered Zuley's alleged involvement in the torture and forced confessions of several homicide cases in Chicago.

[90] Memos Zuley wrote, quoted in the Senate Intelligence Committee's report on the CIA's use of torture, described him using "stress positions"—the shackling of interrogation subjects in painful postures for extended periods of time.

The Guardian reported in February 2015 that the Chicago Police Department "operates an off-the-books interrogation compound, rendering Americans unable to be found by family or attorneys while locked inside what lawyers say is the domestic equivalent of a CIA black site."

"[92][93][94][95][96][97][98][excessive citations] After The Guardian published the story, the Chicago Police provided a statement saying, without specifics, that there is nothing improper taking place at what it called the "sensitive" location, home to undercover units.

The Guardian said the Chicago Police statement did not address how long after an arrest or detention those records are generated or their availability to the public, and that a department spokesperson did not respond to a detailed request for clarification.

[103] Due to errors or acting on bad or faulty tips without double-checking information, Chicago police have raided incorrect addresses with no-knock warrants more than once in recent years.

[105] While new search warrant policies have been implemented by the CPD, including mandatory pre-checks and additional supervisors, one victim said she still believes the police department has a long way to go, and is "traumatizing Black Chicagoans in the process".
