11.2: Applicable Laws Governing Use of Force

Criminal behavior within California prisons is governed by a structured legal and administrative framework outlined in Title 15 of the California Code of Regulations (CCR), which is enforced by the California Department of Corrections and Rehabilitation. While incarceration is intended to confine individuals for prior offenses, it does not eliminate the possibility of new crimes being committed inside correctional institutions. In fact, the CCR establishes clear rules that not only define prohibited conduct but also create a pathway for serious violations to be referred for criminal prosecution. As a result, inmates who engage in criminal acts while incarcerated may face both internal disciplinary consequences and additional charges in state court.

Assault and Battery

One of the most prevalent and serious crimes committed in prison is assault, which includes both inmate-on-inmate violence and attacks on correctional staff. Under CCR §3005 (Behavior) and CCR §3315 (Serious Rule Violations), inmates are required to obey all laws, and any act of violence is considered a serious rule violation. Assaults can range from simple physical altercations to aggravated attacks involving weapons or resulting in significant bodily injury. When staff members are targeted, the offense is treated with heightened severity due to their status as peace officers. Incidents are typically documented through medical reports, staff observations, and Rules Violation Reports (RVRs), which serve as the foundation for both disciplinary action and potential referral for prosecution under CCR §3323 (Referral for Prosecution). In many cases, these acts lead to felony charges that can significantly extend an inmate’s sentence.

Weapons Possession or Manufacture

Another major category of in-prison crime involves the possession or manufacture of weapons. Inmates often create improvised weapons, commonly referred to as “shanks,” from everyday materials found within the facility. CCR §3290 (Contraband) and CCR §3315 (Serious Rule Violations) prohibit the possession of any item that can be used to inflict harm, whether manufactured or altered. These weapons are typically discovered during routine cell searches, metal detector screenings, or intelligence-driven investigations. The presence of such weapons is often linked to planned acts of violence or gang-related activity, making them a serious threat to institutional safety. When sufficient evidence exists, these cases may be prosecuted as felony offenses involving weapons within a penal institution.

Drug Possession and Trafficking

Drug-related offenses also represent a significant concern within correctional facilities. Under CCR §3005 (Behavior), CCR §3290 (Contraband), and CCR §3315 (Serious Rule Violations), inmates are strictly prohibited from possessing, using, or distributing controlled substances. Despite these regulations, drugs continue to enter prisons through various means, including visitor smuggling, mail systems, and, in some cases, staff corruption. Once inside, drugs are often distributed through organized networks, frequently controlled by prison gangs. Detection methods include urinalysis testing, K-9 searches, mail inspections, and intelligence gathering authorized under CCR §3268 (Investigation and Intelligence Gathering). When inmates are found to be involved in drug trafficking or possession with intent to distribute, their cases may be referred for prosecution, sometimes involving outside agencies such as the California Department of Justice. These offenses can lead to new felony charges and additional prison time.

Homicide

Homicide, though less common, represents the most serious form of criminal behavior within prison walls. Under CCR §3005 (Behavior) and CCR §3315 (Serious Rule Violations), any act resulting in the death of another inmate is treated as a major violation requiring immediate and thorough investigation. These incidents are often linked to gang activity, including ordered “hits” carried out as part of organized criminal operations. When a homicide occurs, the prison effectively becomes a secured crime scene, with evidence collection, witness interviews, and surveillance analysis conducted in coordination with outside law enforcement. Cases are referred for prosecution under CCR §3323 (Referral for Prosecution), and convictions can result in life sentences without the possibility of parole or other severe penalties.

Escape and Escape Attempts

In addition to violent and drug-related crimes, inmates may also engage in escape attempts. These offenses are governed by CCR §3005 (Behavior) and CCR §3315 (Serious Rule Violations), and include both successful escapes and attempts, such as tampering with security systems or possessing escape tools. These incidents trigger immediate lockdowns and extensive investigations, often resulting in new felony charges even if the escape is unsuccessful.

Arson and Destruction of Property

Arson and property destruction pose significant risks to institutional safety, as fires or deliberate damage can endanger both staff and inmates. Under CCR §3005 (Behavior) and CCR §3315 (Serious Rule Violations), these acts are treated as major violations. Emergency responses, including fire suppression and evacuation procedures, are immediately initiated, and cases may be referred for criminal prosecution depending on the severity and intent.

Gang Activity and Conspiracy

Gang activity and conspiracy further complicate the landscape of prison crime. Under CCR §3268 (Investigation and Intelligence Gathering) and CCR §3315 (Serious Rule Violations), correctional staff are authorized to conduct intelligence operations to monitor and disrupt organized criminal behavior. Prison gangs such as the Mexican Mafia, Nuestra Familia, and Aryan Brotherhood often orchestrate violence, drug trafficking, and other illegal activities both inside and beyond prison walls. These organizations rely on communication networks, intimidation, and hierarchical structures to maintain control. Participation in gang-related activities can result in conspiracy charges and sentence enhancements, further increasing the legal consequences for involved inmates.

Contraband and Unauthorized Items

Finally, the possession of contraband—such as cell phones and unauthorized communication devices—also plays a role in facilitating criminal activity. CCR §3290 (Contraband) prohibits such items, and their discovery often leads to further investigation into broader criminal conduct. While not always prosecuted as a standalone crime, contraband can enable inmates to coordinate illegal operations within and outside the prison.

In conclusion, the California Code of Regulations provides a comprehensive system for identifying, managing, and prosecuting crimes committed within prison. Through a combination of institutional discipline and external legal action, the California Department of Corrections and Rehabilitation ensures that criminal behavior behind bars is addressed with seriousness and accountability. Inmates who commit new offenses while incarcerated face not only internal sanctions but also the possibility of extended sentences through the criminal justice system, reinforcing the principle that incarceration does not exempt individuals from further legal responsibility.⁵⁰
