All fun stories BUT, the truth is a bear gets a tag in both ears the first time it is handled. Bear, especially the males tend to get tags ripped out from time to time. By using a tag in each ear it is unlikely they will lose both tags and still identifiable.
As for it ripping your camera down that too is very typical of bears. They don't like things that aren't part of the natural surroundings. They will often bust up bird boxes, hunting blinds or tree protective cones when they find them too.
