The fact that this man wAs a marine and one of the officers he killed was also a marine shows the falling of brotherhood within our military men/women.

I remember when serving your country was a calling and afterwards you regarded the men as your brothers.  "Even though nowadays people try to say capt America and buckey barns R gay because of how close they were, (morons that's called brotherhood because you fought and next to each man and that man covered your ass on the field)". 

Now when people serve their country they seem to have forgotten what the core taught them, what they swore an oath to, what they are supposed to believe in.
