I was falsely arrested under the belief of arson. It happened when I was in my early 20s. The charges were dismissed and my expensive lawyer said it was the best deal to end it all. There wasn't even a fire and a cop that made the arrest had no reason to assume I was trying to start a fire. In any case, I still have to wait a few years to even expunge it.
Well, when going through university I was bullied & ostracized for a period of time and eventually found out someone had googled my name. They could see the arrest on some website and just the type of charge it was.
I don't want to trivialize the pain a wrongful arrest ad bullying caused, but I think the solution to the underlying problem is more sunlight, not less. Without being able to see how many wrongful/unfruitful arrests happened at the hands of your arresting officer and DA, power might go unchecked for longer and grow more corrupt.
