Not a good idea. All the resons stated and in most cases you'd just have a very mad bad guy. By the way, when using live rounds and don't (not a good idea either) intend to hurt or wound, fire in a safe direction (not in the air) - near enough to the the supposed bad guy and be ready for a quick follow up if BG turns out really bad. This same discussion was held hear years back over the use of handgun shot-shells: Same answer.
