Obviously, to those who feel that this type of behaviour, (turning video evidence over to an officer), is a slippery slope, It "can" be but let's also remember that there are built in "safe guards" in the system. The officer can view the video evidence and based upon his training, (something MOST posting here have none of), determine if he feels there is sufficient evidence to warrant an investigation. Doesn't mean that charges will be laid it means the officer would then contact, (IF identifiable), the driver in question and investigate, (get their side of the story).
Then if he/she feels sufficient evidence exists to lay a charge he must present his findings to a crown who will decide if charges are laid and the legal system set into motion. Then of course if it goes to trial the JP will determine if sufficient evidence exists to support the charge laid and register a conviction.
Now as Rob eluded to a private citizen may appear before a JP and swear out an information. This has virtually the same effect as the laying of a charge, of course the JP will consider the information it is not "automatically rubber stamped," but it is without Crown review. The crown "may" decline to take this to court or may withdraw the charge once it is in front of a JP.
In this case Bike cop is taking the initiative to build a relationship with the bike communtiy. again YOU, (as the person who shoots the video), has the option of sending ti to him or not. He hasn't indicated he is going to hunt down everyone with a camera and demand the footage..lol.
