Here is a brief quote from Silberman’s opinion:

“When we look at the Bill of Rights as a whole, the setting of the Second Amendment reinforces its individual nature. The Bill of Rights was almost entirely a declaration of individual rights, and the Second Amendment’s inclusion therein strongly indicates that it, too, was intended to protect personal liberty.The collective right advocates ask us to imagine that the First Congress situated a sui generis states’ right among a catalogue of cherished individual liberties without comment. We believe the canon of construction known as noscitur a sociis applies here. Just as we would read an ambiguous statutory term in light of its context, we should read any supposed ambiguities in the Second Amendment in light of its context. Every other provision of the Bill of Rights, excepting the Tenth, which speaks explicitly about the allocation of governmental power, protects rights enjoyed by citizens in their individual capacity.The Second Amendment would be an inexplicable aberration fit were not read to protect individual rights as well.”
