Firearm safety

It seems from a recent article on WKSR that there may need to be some safety classes held for people using firearms in the county. According to the report an officer with the Pulaski Police Department was cleaning their hand gun when it accidentally discharged. There is no possible way a hand gun can fire its self if proper procedures are being followed. Some simple issues of handgun safety is do not think but know by checking if the weapon is unloaded. Never attempt to clean a loaded weapon and always treat a firearm as if it is loaded until you know for certain.
A question arises as to whether the officer involved was following proper procedures.... obviously not. If not why not and was there any disciplinary action taken. Fortunately this did not turn out to be as bad as it could have been but if no changes are made what will the next incident result in?
