Amy is right.
The legal term felony applies to too broad a range of actual crimes to consider the rank of felony alone describing those conditions that should limit 2nd amendment rights. In essence Amy was saying felony was too broad of a term to restrict 2nd amendment rights.
I think Amy may have had federal felony convictions like these (and others) in mind, as not constituting crimes for which 2nd amendment rights should be diminished:
Bond Default
Computer Crime
Concealment of Assets
Contempt of Court
Copyright Matters
Disclosure of Confidential Information
False Statements Relative to Healthcare Matters
False Statement in Application for Unemployment
Lobbying with Appropriated Moneys
Medical/Healthcare Fraud
Partial Birth Abortion
Picketing or Parading
Shoplifting
Suits Against Government Officials
On a more sober note I have always contended that if a person is too dangerous to own a gun, they belong in jail, not on the street.
