The Court of Public Opinion is the court that drives teens to suicide through internet bullying, that accused the wrong man of bombing the Boston Marathon, and killing students at Sandy Hook, even suggesting Sandy Hook didn't happen. That's the internet.
The standards for evidence on the internet are low, and tempers are high. Transparency in "all" public police interactions isn't necessary, just like transparency in "all" doctor interactions isn't necessary in order to judge doctor competency. Its an infuriating distraction; it gives you an excuse to be angry about everything. And moreover; media outlets fuel this outrage machine by purposefully omitting context and nuance in order to drive clicks.
You believe you're using a critical eye to analyze these situations. You're not. This is undeniable, because it is difficult even for the people there, at the scene, to analyze a complex situation like these critically, to have all the information, and understand if the right call was or was not made, let alone someone sitting in a dark room in their basement a thousand miles away getting all of their information from Buzzfeed and The Verge.
Its the job of the Court of Law to look past the Taylor Swift; they're held to a higher standard, just as officers themselves are. That doesn't mean mistakes aren't made. But those mistakes are not an excuse to break the system and raise tensions in every police interaction. This will only lead to more violence.
