YouTube helps solving crimes in Canada

Canadian police used Youtube to hunt down criminals. It was reported that they posted a one-minute video shows "people of interest" entering a Hamilton, Ontario bar, hours before two young men were stabbed in a brawl outside after a hip hop music concert. Another case about street-racers in Winnipeg, Canada, were also charged with dangerous driving after police identified them in taped stunts posted online. They are expected to appear in court next month.
