However, in reality, after police make an arrest, people sometimes wait hours before getting booked and days before getting charged. The drama seems exciting but reality is a different experience.<\/p>\n\n\n\n<p>How long can police hold someone without charges, legally speaking? How long are people held, in real life?

The 48-hour rule is a compromise between opposing interests. On the one hand, people have Constitutional protections that once arrested, they have a right to be charged with a crime or released as soon as possible. On the other hand, the system is overburdened and police work, like any other work, has its share of inefficiencies.<\/p>\n\n\n\n<p>Although the soft limit of 48 hours is a step in the right direction to protect Fourth Amendment rights, the exact criteria for holding people longer than 48 hours remains undefined. For instance, in its rulings, the Supreme Court did not define what an \u201cextraordinary circumstance\u201d might be, and as a result, police have very wide discretion. Our analysis of CPD data demonstrates, to an extent, how police exercise this discretion.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">MAKING SENSE OF CHARGES<\/h4>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignright size-large is-resized\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/chicagocouncil.org\/staging\/1601\/wp-content\/uploads\/2020\/12\/CA27BB5D-1C61-4F55-B2C1-22469807AEB3_1_105_c.jpeg\" alt=\"\" class=\"wp-image-3687\" width=\"458\" height=\"429\" srcset=\"https:\/\/chicagocouncil.org\/staging\/1601\/wp-content\/uploads\/2020\/12\/CA27BB5D-1C61-4F55-B2C1-22469807AEB3_1_105_c-300x281.jpeg 300w, https:\/\/chicagocouncil.org\/staging\/1601\/wp-content\/uploads\/2020\/12\/CA27BB5D-1C61-4F55-B2C1-22469807AEB3_1_105_c-768x719.jpeg 768w, https:\/\/chicagocouncil.org\/staging\/1601\/wp-content\/uploads\/2020\/12\/CA27BB5D-1C61-4F55-B2C1-22469807AEB3_1_105_c.jpeg 916w\" sizes=\"auto, (max-width: 458px) 100vw, 458px\" \/><\/figure><\/div>\n\n\n\n<p>To understand what constitutes an extraordinary case, we first wanted to find what the data says about the average case. In the preceding donut chart, we classified thousands of unique charge descriptions into eight high-level buckets: Warrants\/Failures to Appear (FTA), Gun Possession, Vehicle\/Traffic, Battery, Trespassing, Retail Theft, Cannabis, DSL, Domestic Violence, and Narcotics. Drug charges (Narcotics and Cannabis) accounted for most cases overall, followed closely by court-related (Warrants and FTA) and property (Trespass and Retail Theft) charges. When the same data is filtered for holding times longer than 48 hours, battery and assault (\u201cperson charges\u201d) account for about 50% of all cases. Similar to the high-level breakout, subcategories of \u201cperson\u201d and \u201ccourt-related\u201d charges account for most cases; this analysis focuses primarily on a classification of these lead charges.<\/p>\n\n\n\n<p>Based on an analysis of lead charges by arrest to release times, the finding may be two-part. At a high-level, \u201dperson charges,\u201d or those allegations commonly associated with violence against another person are more likely to be considered extraordinary and subject to holding times greater than 48 hours. However, at a more detailed level, there does not appear to be a meaningful difference in holding times by charge. In other words, based on a classification of lead charges, it is unclear what types of charges constitute an extraordinary case subject to excessively long holding times.\u00a0<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">CHARGES BY RACE<\/h4>\n\n\n\n<p>If the lead charge classification does not define an extraordinary case, then what else might explain the difference? Based on an initial analysis, when arrest-to-release hours are categorized by race, the data across all racial categories all have similarly skewed distributions [<em>See Figure 5<\/em>].

The 48-hour&nbsp;<em>soft rule<\/em>&nbsp;may protect some people\u2019s Fourth Amendment rights, but based on the data, it doesn\u2019t appear to go far enough in Chicago. The definition of&nbsp;<em>extraordinary<\/em>&nbsp;can be completely arbitrary.&nbsp;<strong>According to the data, in more than 99% of all cases, Chicago police hold people for less than the threshold; however, there are thousands of other cases that troublingly go for hours \u200a\u2014\u200a&nbsp;<em>or even days<\/em>&nbsp;\u200a\u2014\u200a past 48 hours from the initial point of arrest.<\/strong><\/p>\n\n\n\n<p>Given the ambiguous nature of \u201cextraordinary circumstances,\u201d we analyzed arrest records to see if patterns in the data reveal something about how police interpret such circumstances. Our initial findings indicate that, for the most part, arrests with holding times in excess of 48 hours are no different than any other arrest. These findings are based on an initial, two-tiered classification of the lead charge in a given arrest. Further, the arrest records for holding times generally reflect the same disparities in race seen throughout the system, suggesting almost no difference in arrest holding times that exceed 48 hours by race. As a result, our initial conclusion is that&nbsp;<em>extraordinary<\/em>&nbsp;arrests are loosely based on (1) the type of charge, (2) arbitrary, (3) divided along race, or a combination of the three.<\/p>\n\n\n\n<p><strong>Despite the initial conclusion, a geospatial analysis of the same data suggests that both location and race might actually explain differences in holding times. The longest arrest holding times belong to Chicago Police District 2 (Wentworth), District 7 (Englewood), District 4 (South Chicago), District 5 (Calumet), and District 12 (Near West),&nbsp;on Chicago\u2019s West and South Sides. In the absence of other compelling variables, is it possible that race and location have more to do with incommunicado detention than the actual crime?<\/strong><\/p>\n\n\n\n<p>At this time, this analysis is inconclusive, but we leave you with four points:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li>The data herein represents a tremendous opportunity for analysis but is still incomplete because there are data quality issues that require further investigation and scrutiny\u200a\u2014\u200afurther peer review of our analysis is both necessary and welcome.<\/li><li>Since both the law and data suggest that \u2018extraordinary cases\u2019 are either arbitrary or racially divided, there may be an opportunity for civilian oversight on police practices as they relate to arrest holding times.<\/li><li>At this stage of analysis, it is still not clear what factors are responsible for very long holding times\u200a\u2014\u200aquestions along this topic may inform next steps in research.<\/li><li>Finally, as we continue to research this dataset and explore relationships to court reform, we are interested in your comments and collaboration.<\/li><\/ol>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong><em>Data Availability &amp; Methodology:<\/em><\/strong><a href=\"https:\/\/github.com\/justinhchae\/appleseed_public_arrests\"><em> <\/em><\/a><a href=\"https:\/\/github.com\/justinhchae\/appleseed_public_arrests\"><em>https:\/\/github.com\/justinhchae\/appleseed_public_arrests<\/em><\/a><\/p>\n\n\n\n<p style=\"font-size:12px\">DISCLAIMER: This site provides applications using data that has been modified for use from its original source, www.cityofchicago.org, the official website of the City of Chicago.&nbsp;The City of Chicago makes no claims as to the content, accuracy, timeliness, or completeness of any of the data provided at this site.&nbsp;The data provided at this site is subject to change at any time.&nbsp; It is understood that the data provided at this site is being used at one\u2019s own risk.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>INCOMMUNICADO DETENTION Arrested and deprived of communication without being charged  [&#8230;]<\/p>\n","protected":false},"author":2,"featured_media":3678,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"nf_dc_page":"","footnotes":""},"categories":[78],"tags":[13,9],"class_list":["post-3676","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-collaboration-for-justice","tag-criminal-justice","tag-police-accountability"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>We analyzed 536,000 CPD arrest records spanning a period from 2014 to 2020.
