In fact, Halifax's deputy chief of police suggested that the federal government urge caution in the use of citizens' arrest. This is not only to ensure that a well-intentioned person does not commit a crime, but also to remind people that an arrest involves risks and that an ordinary person is not as likely as a police officer to be able to get control of someone who has committed a crime.
Il s'agit non seulement d'éviter qu'une personne bien intentionnée commette elle-même un crime, mais aussi de rappeler qu'une arrestation est une opération qui comporte des risques et qu'un citoyen a peu de chances de maîtriser celui qui a commis le crime aussi bien qu'un policier.
