If displaying Indian bric-à-brac is this big of a deal then the laws need to be rewritten. Too much deference is given to the Indians in law already.
In Central KY there was a large Indian burial ground off limits to diggers. Over one weekend it was the site of a massive dig. I knew my friends hobby was Indian artifacts. Putting 2 + 2 together called his house spoke to the wife and he was gone, gone, gone. Never heard from him or of him again. Still wonder what happened to him. Heard the stuff that went amiss was worth a ton. Several newspaper articles at the time.
Sometimes a mans got to do what a mans got to do.
