That doesn't really address the issue, though. The issue is that people can be shown to have been at the police station at all.
Maybe in the best of times this would seem a bigger concern, but in the present day it definitely seems like there needs to be more pressure on police to meet minimum standards.
I think that's a bit more than can be reasonably expected of someone who is in active danger and afraid.
There does need to be some way that people can go to the police without being at risk of exposure by "first amendment auditors", but it's hard to see how that could happen. The people doing the recording would probably demand the right to record in any other place that is set aside for such purposes as well.
That's why this is a really difficult issue. The ruling may be technically correct, but it seems to me that this practice does more harm than good.
