The or remain addition ruins it, though I also don't see that holding up in court with any reasonable jury. In that scenario, if I start more than 25 feet away and stand my ground if a cop approaches me only with the intent of making me move or stop filming, I've truly done nothing wrong and the cop is intending to infringe on my rights.

Will a judge or DA see if this way? Almost certainly not. But if I were on the jury I'd throw that shit out, I don't really care what the law says as written if its a law I don't think is constitutional or reasonable. Juries are there, in part, to act as a check on the legal system.
