The Men's Central Jail (MCJ) and Twin Towers Correctional Facility (TTCF) are located in a dense cluster next the rail yard northeast of Union Station.

Twenty-three-year-old male Gabriel Carillo was severely beaten and pepper sprayed by a deputy in Men's Central Jail on Saturday, February 26, 2012.

[21] An issue that arises with the incarceration of individuals with mental disorders is that they must be tested for competency before they can be put on trial, which can leave inmates in jail for longer than necessary.

[22] Richard Lamb and Robert W. Grant conducted a similar study of 101 women that are imprisoned in the Los Angeles County Jail system.

[25] One solution to this issue could be opt-out screening and vaccinations for STIs and other infectious diseases, which has the potential to improve health conditions in jail and in surrounding communities.

This complex resulted from a network of racialized criminalization, and the punishment arrived from institutions of authority that patrolled and incapacitated Black and Latino youth.

Villanueva has never acknowledged membership in the Banditos deputy gang, but did admit to being a member of the "Cavemen" while stationed in East Los Angeles.

[30][31] A 2020 county inspector general report concluded that the Banditos gang at the East LASD station were "gang-like and [that] their influence has resulted in favoritism, sexism, racism and violence.

"[32] The first deputy gang acknowledged by the LASD was the "Little Devils" in an internal memo in 1973, although they are believed to have been involved in the death of Los Angeles Times reporter and law enforcement critic Ruben Salazar during the National Chicano Moratorium March against the Vietnam War on August 29, 1970.

[30] They operated out of the East Los Angeles station and sported tattooed caricatures of a small, red devil on their left calves.

[33] The "Wayside Whities" operated out of the Peter J. Pitchess Detention Center throughout the 1980s, their alleged mission being to "bring to heel" any incarcerated black men, especially those who fought with white prisoners.

[35] Former Undersheriff Paul Tanaka, who also served as the mayor of Gardena, California, is identified as a member of the Lynwood Vikings, and was convicted of federal obstruction charges in 2014.

[36] In July 2021, U.S. Representative Maxine Waters called for a United States Department of Justice investigation into allegations that a violent deputy gang known as the Executioners was running the Compton station of the LASD.

Despite her imposing physique, Dole remained in a passive stance with her arms folded in the middle of the street, where the video showed her being beaten to the ground with police batons and flashlights.

[41] In December 2009, the L.A. Times reported that L.A. County Auditor-Controller Wendy L. Watanabe's office found 348 deputies worked more than 900 hours of overtime between March 2007 and February 2008.

[44] In September 2010, three deputies (Humberto Magallanes, Kenny Ramirez and Lee Simoes) pleaded no contest to charges related to their beating of a prisoner in 2006.

[45] In December 2010, members of a widely known gang-like group of L.A. County Sheriff's Deputies known as 'The 3,000 Boys' were involved in a violent fight in the parking lot of the Quiet Cannon Restaurant in Montebello.

The '3,000 Boys' is a name referring to a gang of L.A. County Sheriff's Deputies and Jailers who have been involved in the beatings and organized fights of inmates in the 3,000 block of the Men's Central Jail in Downtown Los Angeles.

In May 2011, six deputies were suspended without pay (pending termination and criminal prosecution) for the beating of Evans Tutt, an inmate who had been filing complaints about living conditions within the jail.

[46] In January 2011, Deputy Patricia Margaret Bojorquez was sentenced to a year in custody for making a false police report against her husband and recklessly firing a gun in her home.

[47] In April 2011, Deputy Sean Paul Delacerda was convicted of breaking into a woman's home kidnapping, assaulting her with a handgun and falsely imprisoning her.

[51] In May 2012, part of the Gang Enforcement Team was accused of being a clique called "Jump Out Boys" after a pamphlet was discovered indicating that members would receive a tattoo after being involved in a shooting, glorifying the incident.

Reserve sheriff's deputies are issued a badge, an identification card, uniforms, a Smith & Wesson M&P[67] duty weapon, handcuffs, baton, and other equipment.

Reserve deputy sheriffs may also qualify for shooting bonus pay of up to $32.00 per month, and some paid special event assignments are occasionally available, as well as overtime.

[68] Shortly after the M&P's adoption, LASD deputies experienced a rash of accidental discharges in the field, later attributed by the Inspector General's office to insufficient weapon transition training for sworn personnel.

[69] Prior to 1991, the standard sidearm of the LASD was the Smith & Wesson Model 15 Combat Masterpiece revolver in caliber .38 Special, with blue steel finish, four inch barrel, and adjustable sights.

From 1947 on, patrol cars were issued with the Ithaca 37 Pump Action "Deerslayer" shotgun with 20 inch barrel, loaded with four rounds of "00" (double ought) buckshot.

Until the department switched to semiautomatic sidearms, Sheriff's Deputies were permitted to purchase any Colt or Smith & Wesson revolver with a 4-, 5-, or 6-inch barrel, provided only department-issued ammunition was used in the weapon.

[71] The Special Enforcement Bureau (SEB) is the LASD's equivalent of a SWAT team, which was originally a creation of the nearby Los Angeles Police Department during the 1960s.

Forty-two of the eighty-eight cities in Los Angeles County contract with the Sheriff's Department for their complete municipal law enforcement services.
