Straw-man / improper description. You are not asking for permission to sell or transfer. You (by compliance) are insuring, you are not transferring to a known risk, doing your part to prevent you having something to do with supporting domestic or international terrorism, criminal activity, or passing weapons to those mentally or emotionally unfit to be trusted with them. If your neighbor left his loaded gun available for his kid, who got mad and shot your kid, would you hold your neighbor responsible? Same in society. You are morally or legally responsible for every bullet you fire or weapon that leaves your control at least for first level.
Sorry....any fee for the exercise of a Right is a violation of the Constitution.....
If my neighbor left his gun out we have laws that deal with that......the Constitution doesn't protect negligence.....
The criminal already knows they can't buy, own or carry a gun, and we can already arrest them.....
So...according to your theory, all computer and electronic device sales need to have background checks before they are completed.....right? Before you are allowed to by an Ipad, computer, laptop, or any other tablet......you must have a criminal background check, since computer criminals are often sentenced such that they can't use computer anymore. Dittos making sure you aren't selling a computer to a child molester, a terrorist or a convicted identity thief...right?
You are morally responsible for every tap on a key board that leaves your control....so from this point forward, Best Buy, Amazon will conduct background checks on all sales...right?
