The purpose of this study was to determine how American and Canadian robbery detectives collect identification evidence and whether their practices are consistent with published guidelines. Via a survey, we asked about the use of various lineup practices (e.g., single-blind vs. double-blind
administration, sequential vs. simultaneous presentation, and videotaping). Canadian detectives are more likely to use research-based reforms such as double-blind sequential lineups and videotaping. We also assessed how robbery detectives interact with eyewitnesses at four points during a
lineup: prior to the lineup, immediately after an identification, and after 12 seconds and 3 minutes have elapsed without an identification. Results showed that at the latter two junctures, officers from both the countries question eyewitnesses in subtle ways that could influence the likelihood
of choosing and confidence in the selection. Canadian detectives are less likely than American detectives to do so, however. This finding can be explained by the absence of written guidelines in most US jurisdictions on how officials should interact with eyewitnesses during lineups.
