Request #RT-12210
Under the California Public Records Act, I am requesting a "data dictionary" for a prior request I made for Oakland Police stop data, which has since been closed (Request #11675). I would like definitions for the different fields in the columns labeled: "ReasonForEncounter", "ResultOfEncounter" and "TypeOfSearch". I am also requesting a copy of the Oakland Police Department's policy on stopping vehicles and searching motorists. Thank you for your time and help, and please let me know if there is anything unclear about the request.

The “ResultofEncounter” fields are as follows: • Felony Arrest – Arrest for a serious crime as defined in the CA penal code and the arrestee taken into custody. • Misdemeanor Arrest – Arrest for a “less serious” misdemeanor crime as defined in the CA penal code. These arrest may lead to a person being taken into custody or cited and released. • Citation – A citation was issued, often for traffic violations or misdemeanor offenses. • Warning – A warning was issued with no further action, often for traffic violations. • FI Report –A Field Interview report was completed and no additional action may have been taken. • Report Taken - No Action – A report was completed with no additional action taken. The “TypeOfSearch” fields are as follows: • Incident to Arrest – These are warrantless searches conducted during or immediately after a lawful arrest of an arrestee. As outlined in the 1969 case of Chimel v. California: When an arrest is made, it is reasonable for the arresting officer to search the person arrested in order to remove any weapons that the latter might seek to use in order to resist arrest or effect his escape. Otherwise, the officer’s safety might well be endangered, and the arrest itself frustrated. In addition, it is entirely reasonable for the arresting officer to search for and seize any evidence on the arrestee’s person in order to prevent its concealment or destruction. And the area into which an arrestee might reach in order to grab a weapon or evidence items must, of course • Prob/Parole – These are based on the detainee’s probation/parole search conditions. • Weapons (Also known as Pat Searches or Cursory Searches) – These are conducted when officers reasonably believe that the lawfully detained person is armed and/or dangerous or the officer or another is in danger of physical injury. The officer may search the outer clothing for weapons and may temporarily recover the weapon. • Probable Cause - Probable cause is the legal standard by which a police officer has the right to make an arrest, conduct a personal or property search, or obtain a warrant for arrest. While many factors contribute to a police officer’s level of authority in a given situation, probable cause requires facts or evidence that would lead a reasonable person to believe that a suspect has committed a crime. Common examples of probable cause include the sight or smell of contraband in plain view or plain smell, or an admission of guilt for a specific crime. The presentation of any of these facts would allow an officer to perform a search and make an arrest. • Inventory – These are mandatory searches conducted to log and preserve property in a vehicle prior it being towed and impounded.

Attached are a copy of OPD Report Writing Manual R-1 which outlines the different stop data fields for “ReasonForEncounter” on pages 8 and 9. When officers mark “Probation/Parole” for ReasonforEncounter, it means the officer has prior knowledge that the detainee is on probation or parole. Also attached is OPD Training Bulletin I-O.4 which outlines probation/parole searches.
