I'm of the same mind really. I don't even have an issue with someone owning 280 guns tbh. Collections are a thing and quality guns hold their value extremely well. Obviously someone under investigation for multiple homicides shouldn't have full access to his 280 guns but I also kind of think they should let him sell them; they're his and he's entitled to adequate legal representation (which is expensive).
"The defense’s motion was filed in response to a prosecution motion asking the court to allow the transfer of Heuermann’s guns and other firearm items to the Nassau County Police Department...the defense cited precedent in their motion, stating, 'When property is no longer needed as evidence, the government must establish, in an appropriate proceeding, an independent interest to justify any further retention' and reminded the court that prosecutors said that they no longer needed the property as evidence. "
AFAIK his MO didn't involve shooting so the guns aren't that relevant, he's not been convicted of anything, pigs just want the guns .
