Sure, it won't hold up in court if they take you to jail, but it could possibly make your life hell for 24 hours at the very least.
You could lose your job being detained, for example. IIRC they can hold you that long with no justification or reason required, but I'm not a laywer so take that with a grain of salt.
Or weeks, if they really wanted to fuck with you. Just leaving a patrol car around your house for awhile is pretty unsettling.
Maybe I'm overthinking this. I certainly don't want to get on the wrong side of my local PD. I don't even want them to know my name, much less stop me every time they see me or otherwise retaliate against me because I whipped out a cell phone.
It's almost like a chilling effect, if I have that concept right. I might be mixing that up with another term. Thinking of police retaliation makes me not want to record the police at all, out of fear of retaliation.
