There is a loop-hole, it is called the first amendment a.k.a. the freedom of speech. I
Yeah... That doesn't work. Similar to how the first amendment doesn't protect against libel, copyright infringement, child pornography, & other illegal things.
Trust me, whole legions of lawyers are going after these
stupid laws, but while it's fairly easy to get around them in public? In the case of Domestic Violence? It's freaking insane. Not even thousands of hours of family video count as
implied consent... Because all the abuser has to do is say that they didn't give their consent to be filmed committing a crime (and why would they? That holds too much water in court). The local police are being incredibly good/ helpful in not getting video thrown out immediately (Honey? I didn't see this, you may have
tried to show me but I was too busy talking to my partner, okay? I didn't see it. Show it to your attorney. Make sure to tell them I didn't see it, none of us saw it, we were too busy, right Mike? // Whaddareya talking about? See what? You think I have time to be watching shit? I'm here interviewing a very believable story. Why would I need video to believe it?.) & in tricking abusers into admitting some kind of consent to their victims filming them so it
can be used against them... Or better yet, straight up confessions of guilt. But DV is an uphill battle from start to finish.
