Let's call them what they are:

117. The book is by a legal scholar...here's some more...there are many cases...it's legal.

There's no right for dangerous people and children to have any guns they want. There's no "2nd Amendment" claus that dictates the method to restrict guns. Simple. Read the book...and the references in the book. You'll see. Even Scalia admitted restrictions were legal on guns.

Americans Don't Have the Right to Bear Just Any Arms

* Ban accessories that serve no purpose other than to transform guns into weapons of mass slaughter, such as attachable drums that carry 100 rounds.
* Adopt rules that make it harder for criminals and the mentally ill to obtain firearms.
* Outlaw the public display of weapons.
* Allow the concealed carry of guns using the “shall issue” standard.
* Stop trying to ban scary-looking add-ons that primarily protect the shooter, but don’t make the gun more dangerous to others.
* Forget attacks on the “armor-piercing bullets.”
* Abandon efforts to outlaw “assault weapons”—a politically loaded phrase with a mishmash of meanings that pretty much amount to nothing.
Scalia clearly stated in Heller that the right to bear arms had boundaries. “Like most rights, the Second Amendment right is not unlimited,” he wrote. “It is not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose.” For example, he cited laws that prohibit the possession of firearms by felons and the mentally ill, or that forbid them in places such as schools and government buildings, or impose conditions on their sale. He also wrote that his decision did not overrule the holding in the 1939 Miller ruling that the sorts of weapons protected are those in common use at the time, and that the “historical tradition of prohibiting the carrying of dangerous and unusual weapons” was still permissible.
In other words, even one of the modern era’s most conservative justices says gun enthusiasts are wrong when they claim that any limitation on firearms is unconstitutional. Government can place restrictions on firearms with the intent of protecting society.
Unfortunately, the NRA has been working for years to make sure lunatics and felons can obtain guns as easily as possible. After the deadliest shooting in American history took place at Virginia Tech (32 dead), Congress passed the NICS Improvement Amendments Act of 2007. When introduced, the legislation called on states to submit mental-health records to national databases maintained by the FBI. The NRA declared this violated the Second Amendment and, through intense lobbying, limited the definition of mental illness only to people institutionalized or found by a court to be a danger. Even if a psychiatrist believed a patient posed a threat, nothing could be done to keep a gun out of that person’s hand.
