Sadly 4 Corners is no less susceptible to unbalanced reporting than any other current affairs show. Its just a bit more polished in its presentation than those that have a 24 hour turnaround time.
The news media is not about providing accurate information, its about grabbing the entertainment dollar (if commercial) or presenting a particular social viewpoint ( if community owned).
As an earlier poster alluded, a great part of the problem is in the editing, which can turn a finely crafted and deadly accurate but otherwise bland piece into a wildly innacurate but sensational head line.
The owners prefer the latter as sensational sells.
