CS,
I normally don't post in forums about these type of things (for reasons that will be come obvious here) but I thought you might like my insight. You see I have been a police officer for 24+ yearsin a busy, high crime area. In Florida. I know that may not be popular with some but hey. Most of that time in South FLorida in the Ft. Lauderdale area, I patrolled a crack ridden, high crime area for about 4 years and then transfered to Homicide, were I was for 7 years.
That said here is my insight into this type of crime/incident. There is a place inside each of us that contains a very violent, animalistic being. In most of us that is suppresed and controlled by our other feelings, compassion, honor, right and wrong and so on. But in some of us there is a time, a place, or an incident that triggers that animal response, and we lose control of the inner animal. Some of us have a higher threshold for that trigger and some of us have a lower trigger point. I have seen things that some humans have done to others in the name of love, hate, anger and such that would make you lose sleep for years. I have. Nightmares also. Some just lose it. Are they insane? I don't think so, I think they have just let that animal inside come up to the surface and take control. Even if its only for a short time. This man that killed his family and tried to kill the ex-wife and son, he lost control of that animal. He needs to be put away or killed depending on your view of the capital punishment issue (thats a whole seperate forum).
I think that maybe we need a little more dose of this now and then to realize that it is out there and we need to be careful. Just know that it is out there and there are those of us that take care of people like this, shall we say taking the trash out. Next time you hear of a story like this and think how awful, think about the poor sap of a cop who had to be the first one on the scene and deal with the death and injured. Makes the pay seem like a whole lot less. As long as we are humans we will have these type of incidents.
God take pitty on his soul and those of his victims.
