It's not that hard to understand. This guy was preventing cops from doing their jobs effectively. A job they felt was important. It's easy to see him as a trouble maker that is enabling other people to more easily break the law without punishment. So they sought out a way to prevent him from doing that.
I'm not saying what they did was OK. I'm just saying it's easy to understand why it happens.
