Wanna play good cop bad cop?

They are in the news all the time. We see officer involved shootings, and cops who dive into freezing water to save a dog. I have been inspired to see how many bad cops we can post, how many good cops.
Here are the rules:
Each story must be true, and possible to verify through reliable news sources. If the last story posted is about a good cop, the next story posted has to be about a bad cop, and so on. Comments can be posted about any of the stories in between, but must be whispered so the last cop post can be easy to locate. Links to stories, videos, etc. about the cop are welcome. Please do not rely on link only, however. If a link is provided, please still describe the story in enough detail so everyone can have at least a general idea of what the story involves.
In comments, please include the name of the officer you are commenting about, along with good or bad.
I will start with a tear jerker story of a good cop, so you can see how.
