Beheler (in regards to what constitutes custody in the requirement to read Miranda rights) but also in other federal court cases related to Miranda law and definition of custody. Although Miranda law has roughly defined custody as the "formal arrest or restraint on freedom of movement," colloquial language may be less restrictive in the use of custody and is thus sometimes difficult to distinguish from the process of arrest. In addition to collecting data on those who have died in custody, the Bureau of Justice Statistics also tracks all deaths related to arrest. This aids in collecting data from the fringes of custody or attempts to arrest an individual. Causes of death The causes for death in police custody may range from suspected homicide by members of the police, killings by other inmates, death due to psychological or physical abuse, capital punishment, to suicide, accidental death, or natural causes. The United States Bureau of Justice Statistics collects data regarding both the cause of death, as well as medical and criminal records of those that die in police custody (restricted to those in federal prison and local jails). Estimates The Bureau of Justice Statistics estimates that 17,358 individuals in custody died during the period from 2007 to 2010. Other publications focus on the rate per 100,000. US jails report deaths that total a mortality rate of 128, and prisons at 264 per 100,000. There are differences in methodology used to obtain these statistics, as some jurisdictions include deaths during attempted arrests, while others do not. Other research has focused on specific states, such as Maryland and the rate of death by identity (gender, race, age). Based on some findings, African-American males appear to be over-represented as victims of sudden custody deaths. Further research with larger sample sizes is necessary. Watchdog organizations The
