While we may not like the fact that the guy sold it to a believed felon, he wasnt a gun dealer. Look past this particular arrest and see whats in the future for New Yorkers that have a sizable collection of weapons with "Military Features". How the heck can you comply with that law when it fully kicks in unless your a gun dealer? Its OK to sell it to anyone in another state or take it out of state to sell it but otherwise, few options to liquidate without huge losses or risk of breaking other laws exist for the private Gun Owner.
Add to that New Yorkers that try to comply will be flooding the markets in other states with weapons as this moves forward. Some will be done via FFLs but most will be private untraceable sales. Its a whole new nationwide black market in the making and Andy Dont Care! Everyone has said this before, I will say it again, Al Capone, The Kennedy's and The Mafia all prospered because of laws just like this, JQ Public just bled in the street!
