No need to imagine. There are innumerable cases over the years where cops have turned into stalkers backed by the power of the government when their girlfriends dump them. It happened to one of my ex-es, but I've seen it in newspapers dozens of times over the years.

The problem is that cops are still people. And people are often messy, emotional, irregular, obsessive, mean, or just have a bad day and need someone to take it out on.

Wetware will be wetware. All we can do is advocate for better training and smarter policies.
