The "Security of a Free State."

"A Well Regulated Militia, being Necessary to the Security of a Free State"

A select militia, particularly if it existed to the exclusion of the citizen militia, might undermine the free state, if citizens excluded from it were left defenseless, or if it disarmed the citizens and infringed their other rights (or both).

Like the police, FBI, ATFE, DEA, etc.? And laws restricting or banning firearms?
