This video was posted online by the Toronto Police Service in the search for witnesses to a murder. The footage has certainly received a lot of hits; a voyeurism which has shocked Canada. Warning, the images might be upsettting. 

It's been branded "Hollywood meets homicide", and police in Toronto hope it could be the key to taking the fight against crime into the 21st century. Videos taken with mobile phones or CCTV cameras are now being made routinely public on the homicide squad's website - a controversial step which cops see as a way of harnessing the power of new media to mobilise a younger generation of crime-spotters, but a step which some find insensitive. This week, shaky video footage of a dead stabbing victim in a Toronto car park was released in the hope that viewers might bring in new leads. Twenty-two-year-old Reon Paul was attacked in the aftermath of Ghana's 2006 World Cup victory but his killers were never found. Investigators hope the graphic video could finally put them behind bars.  

Other videos put online by the police department

An arson attack in Toronto last year filmed by CCTV in 2008.

This video provides startling evidence of a shooting in which six people aged 18 to 21 were hit and one of them, 18-year-old Abdikarim Ahmed Abdikarim, was killed.

"Some may say that it encourages voyeurism (…) but will it get the desired results? More than likely"

Detective John Biggerstaff of the Toronto Homicide Squad.

We encourage our investigators to use new media to capture the attention of the public - particularly among the web-savvy, computer-literate under-30s. It is not for entertainment and not for sensational purposes; it is designed to attract the greatest number of hits possible so that the case has the best chance of being solved. Some may say that it encourages voyeurism, and that's a fair statement. But will it get the desired results? More than likely. Nothing ventured, nothing gained. By taking people back to the crime, it helps us keep the investigation active. It's not so much to make people realise they were there at the time...but to appeal to the consciences of people who may not have been there but who do have information relevant to the investigation. In a way it's a primer."
