How could this of happened.............are firearms allowed at the Chiefs training facility..............are there signs posted..................I'm sure the training facility is off limits for weapons. Rules, signs, ect.... are only followed by those who choose to obey them. Its no fault of the management, team members, the manufacturer of his firearm, or ANYBODY else that he chose the path he chose that day. The blame lies soley on the individual, period. There are enough rules, laws, ect....to keep this kind of situation from happening, IF they are OBEYED. A person who's mind is hellbent on doing wrong, wont be deturred.........as in this situation. People will always want and need to blame SOMEBODY, when something like this happens.Because, there is no way he could have done something like this, he wasnt like that..........it wasnt his fault. Well the fact of the matter is, it was his fault, he did it, it may seem out of character, but for him, that day, at that time,in his state of mind, that was in his character.
