23 Arrest & Detention Procedures Dealing with Suspects

24 Questioning the Accused  Police MUST question suspects, but cannot FORCE suspects to answer.  Section 7 of the CCORAF: right to remain silent.  Police must promptly inform suspects about the reason for the arrest.  He/she also must be read his/her rights – once that happens, anything he/she says can be used against him/her.

25 Interrogation Techniques  Open-ended, non- threatening questions, followed by specific questions.  Four-stage approach is use, where suspect is asked to describe: 1. Entire incident 2. Period prior to offence 3. Details of offence 4. Period following offence

26 Arrest & Detention Procedures  Arrest: deprived of liberty  Making lawful arrests: 1. Identify him/herself as a police officer 2. Advise accused he/she is under arrest 3. Inform accused of charge and show arrest warrant 4. Place hands on accused – shows custody 5. Read rights

27 Arrest & Detention Procedures  Detention: legally depriving a person of liberty to ask questions  Reasonable Grounds must be present for either arrest/detention.

28 Three Methods of Apprehending an Offender

29 Appearance Notice  Legal document telling the accused to appear in court on a certain date.  Accused must sign.  Bench warrant – if accused doesn’t show.  Used in summary conviction and less serious indictable offences.

30 Arrest with Warrant  For serious indictable offences.  Police ask judge/JOP for a SUMMONS, telling accused to show in court.  ARREST WARRANT – if police believe accused won’t show up in court willingly; must provide INFORMATION.

31 Arrest without Warrant Three Circumstances: 1. Reasonable grounds to suspect accused has either committed an offence or is about to. 2. Catch a person in the act. 3. Person may be named on an arrest warrant.

32 Citizen’s Arrest  Most common: catching shoplifting  (store detective/salesperson)  Immediately following the arrest, the suspect must be turned over to a PEACE OFFICER.  Happens rarely.

33 Searches Searching a Person Searching a Place

34 General Rules:  Charter rights must be protected.  Police usually must obtain a warrant.  There are exceptions.

35 Searching a Person  Police don’t need a warrant if they’ve just arrested the person.  Impaired drivers must submit to a breath sample; otherwise, a warrant must be obtained.  Police may carry out a ‘pat-down’ to make sure no weapons are present.

36 Searching a Place  In most cases, police must obtain a warrant.  It must be done by the book or else the evidence it uncovers is inadmissible.  Warrant Rules:  Sworn information must be given to judge.  Police must identify themselves and show warrant.  Telewarrant – given by phone/fax in emergencies. Two Exceptions: 1. Imminent injury/death of a person may result 2. Evidence may be getting destroyed inside
