There is a certain amount of victimization everyone needs to accept (Or take personal responsibility to avoid) to maintain a decent check against oppression, yes. I'm sure we'd all be safer if police put booths on every street that forced people to stop and show papers. But is it worth the trade off?
The same arguments I use against people who would willing cede most of their privacy for some protection against a new 9/11 would be one I use here. The state is a behemoth that crushes things, giving unchecked power to individuals to use it with only their word? Isidiotic. We've literally seen how that works out in history. And guess what? In the end? It NEVER works to help with the original problem, because eventually enough people get caught and victimized by the panic, that there is a back lash against even real victims. If you think there is some scrutiny over rape claims now? Wait until 10 years of a "preponderance of evidence' circus goes by--I mean fuck we are already seeing a huge back lash after 5 years of that JUST in Title 9 cases. Eventually accusations of rape will be treated with disdain and prejudice, not just cold transparency/scrutiny.
Also, the system could use a lot of improvements. You, or anyone, just haven't offered one that doesn't kill the patient. Bad analogy time. You're like someone who wants to pour bleach down someone whose suffering from cancer's throat saying "This WILL kill the cancer, if you're against me administering bleach...you are FOR cancer!"
