Bob McMynn knows first-hand how Canada's laws allow police to eavesdrop and use emergency wiretaps without a judge's approval.
He says Section 184.4 of the Criminal Code helped to save his son Graham's life after a group of young men abducted the then 23-year-old university student at gunpoint in April 2006, in what turned out to be a kidnapping for ransom.
"[The emergency wiretap] was paramount in solving where my son was," McMynn told CBC News. "Without that and other fantastic police work, we may never have got him back."
Vancouver police had little time to ask a judge for permission, so they used the Criminal Code provisions to eavesdrop on a group of key suspects without court approval. Eight days later, police moved in to arrest the gang and free the younger McMynn.
