Ok, lets walk through this slowly since you appear to be having some trouble. Under what policy was it OK for him to enter a private dwelling without permission from the owner occupant? Under what policy was it OK for him to walk in, and then go to the bedroom? Under what policy was it OK to lie about having gone into the dwelling to his supervisors? He was fired for 1) breaking policy, and 2) lying about it when asked about it. Don't know where you work, but for most people, breaking the rules and then lying about it when confronted is a good way to get canned.
If he was concerned about the safety of someone, he could have called the cops who would have proper authorization to go into the home if there was reason to believe there was someone in danger.
please watch the video and understand the context of this case before you make it black and white. the house appeared abandoned, and the lady completely ignored the guy banging on her door. it is any good samaritans duty to check on suspicious activity. how does he know some old lady isnt in the house laying on the ground near death?? remember, he was there BECAUSE the yard was not taken care of, despite written warnings from the county.
just. watch. the. video. it clearly shows this guy is normal and this lady is a crackwhore who thinks shes attractive or something. trust me lady, that guy has no interest in seeing you naked.
