Again, no sympathy or support. If fact, there is no mention of his actions *after* firing. It only addresses his claims about being fired unfairly.
I haven't read every post on the subject, but what I have read is folks who believe that it is possible that he was fired unjustly and those that object to LE's heavy hand (firing on the wrong truck, setting and intentional fire) in dealing with the situation.
So, if there are posts saying, "I sympathize with Dorner and support him killing as many cops as possible" I just haven't seem them.
