Uniformed Services and State Security

It is one of the happy incidents of the federal system that a single courageous State may, if its citizens choose, serve as a laboratory; and try novel social and economic experiments without risk to the rest of the country.

[T]he production of security should, in the interests of the consumers of this intangible commodity, remain subject to the law of free competition.  …  [N]o government should have the right to prevent another government from going into competition with it, or to require consumers of security to come exclusively to it for this commodity.

A question like the present should be disposed of without undue delay. But a State cannot be expected to move with the celerity of a private business man; it is enough if it proceeds, in the language of the English Chancery, with all deliberate speed.
