Background: The Maya civilization was a Mesoamerican civilization developed by the Maya peoples, and noted for its hieroglyphic script--the only known fully developed writing system of the pre-Columbian Americas--as well as for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in an area that encompasses southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. This region consists of the northern lowlands encompassing the Yucatan Peninsula, and the highlands of the Sierra Madre, running from the Mexican state of Chiapas, across southern Guatemala and onwards into El Salvador, and the southern lowlands of the Pacific littoral plain. The Archaic period, prior to 2000 BC, saw the first developments in agriculture and the earliest villages.
Context: The Maya civilization developed within the Mesoamerican cultural area, which covers a region that spreads from northern Mexico southwards into Central America. Mesoamerica was one of six cradles of civilization worldwide. The Mesoamerican area gave rise to a series of cultural developments that included complex societies, agriculture, cities, monumental architecture, writing, and calendrical systems. The set of traits shared by Mesoamerican cultures also included astronomical knowledge, blood and human sacrifice, and a cosmovision that viewed the world as divided into four divisions aligned with the cardinal directions, each with different attributes, and a three-way division of the world into the celestial realm, the earth, and the underworld.  By 6000 BC, the early inhabitants of Mesoamerica were experimenting with the domestication of plants, a process that eventually led to the establishment of sedentary agricultural societies. The diverse climate allowed for wide variation in available crops, but all regions of Mesoamerica cultivated the base crops of maize, beans, and squashes. All Mesoamerican cultures used Stone Age technology; after c. 1000 AD copper, silver and gold were worked. Mesoamerica lacked draft animals, did not use the wheel, and possessed few domesticated animals; the principal means of transport was on foot or by canoe. Mesoamericans viewed the world as hostile and governed by unpredictable deities. The ritual Mesoamerican ballgame was widely played. Mesoamerica is linguistically diverse, with most languages falling within a small number of language families - the major families are Mayan, Mixe-Zoquean, Otomanguean, and Uto-Aztecan; there are also a number of smaller families and isolates. The Mesoamerican language area shares a number of important features, including widespread loanwords, and use of a vigesimal number system.  The territory of the Maya covered a third of Mesoamerica, and the Maya were engaged in a dynamic relationship with neighbouring cultures that included the Olmecs, Mixtecs, Teotihuacan, the Aztecs, and others. During the Early Classic period, the Maya cities of Tikal and Kaminaljuyu were key Maya foci in a network that extended beyond the Maya area into the highlands of central Mexico. At around the same time, there was a strong Maya presence at the Tetitla compound of Teotihuacan. Centuries later, during the 9th century AD, murals at Cacaxtla, another site in the central Mexican highlands, were painted in a Maya style. This may have been either an effort to align itself with the still-powerful Maya area after the collapse of Teotihuacan and ensuing political fragmentation in the Mexican Highlands, or an attempt to express a distant Maya origin of the inhabitants. The Maya city of Chichen Itza and the distant Toltec capital of Tula had an especially close relationship.

Problem: Background: Evers was born July 2, 1925, in Decatur, Mississippi, the third of the five children (including older brother Charles Evers) of Jesse (Wright) and James Evers. The family included Jesse's two children from a previous marriage. The Evers family owned a small farm and James also worked at a sawmill. Evers walked twelve miles to attend segregated schools, eventually earning his high school diploma.
Context: Medgar Evers lived with the constant threat of death. A large Ku Klux Klan and white supremacist population were present in Jackson and its suburbs. The risk was so high that before his death, Evers and his wife Myrlie had trained their children on what to do in case of a shooting, bombing or other kind of attack on their lives. Evers, who was regularly followed home by at least two FBI cars and one police car, arrived at his home on the morning of his death without an escort. None of his usual protection was present, for reasons unspecified by the FBI or local police. Many believe that many members of the police force at the time were members of the Klan.  In the early morning of June 12, 1963, just hours after President John F. Kennedy's nationally televised Civil Rights Address, Evers pulled into his driveway after returning from a meeting with NAACP lawyers. Evers's family had worried for his safety the day of his assassination and Evers himself had warned his wife that he felt himself in a greater danger than usual. When he arrived home, Evers's family was waiting for him and his children exclaimed to his wife, Myrlie, that he had arrived. Emerging from his car and carrying NAACP T-shirts that read "Jim Crow Must Go", Evers was struck in the back with a bullet fired from an Enfield 1917 rifle; the bullet ripped through his heart. Initially thrown to the ground by the impact of the shot, Evers rose and staggered 30 feet (10 meters) before collapsing. His wife Myrlie was the first to find him outside of their front door. He was taken to the local hospital in Jackson, Mississippi, where he was initially refused entry because of his race. His family explained who he was and he was admitted; he died in the hospital 50 minutes later. Evers was the first African American to be admitted to an all-white hospital in Mississippi, a questionable achievement for the dying activist. Mourned nationally, Evers was buried on June 19 in Arlington National Cemetery, where he received full military honors before a crowd of more than 3,000.  After Evers was assassinated, an estimated 5,000 people marched from the Masonic Temple on Lynch Street to the Collins Funeral Home on North Farish Street in Jackson. Allen Johnson, Reverend Martin Luther King and other civil rights leaders led the procession. The Mississippi police came prepared with riot gear and rifles in case the protests turned violent. While tensions were initially high in the stand off between police and marchers, both in Jackson and in many similar marches around the state, leaders of the movement maintained nonviolence among their followers.
Question: why do people think the protection was gone
Answer:
Many believe that many members of the police force at the time were members of the Klan.
