Memory is fallible and therefore a potentially unreliable source of information in a court of law. Much better would be video evidence of a crime. Caruso et al. show that this is not always so, however. Watching surveillance video of a shooting during an attempted robbery in slow-motion replay gave viewers a stronger impression that the shooter fired with the intent to kill, compared with watching it at regular-speed playback. This effect on perception of premeditation was reduced, though not eliminated, by viewing the video at both regular and slow-motion speed, but it was not mitigated simply by indicating elapsed time.

Watching surveillance video in slow motion increases perception of an intent to kill.
