On the gun control issue there are three separate elements. Gun control is a subset of crime. Is gun control possible? What about the second amendment?
Crime seems to be a purely cultural matter. Virtually no crime in Japan. Very low crime among whites, Asian and Latinos in the U.S.. Very high crime rates among male black Americans under 30.
What do we really know about crime?
1) Parenting of black children by single mothers is a major source of black male crime. 2) In the 1990s three strikes laws putting perennial criminals in prison was very effective in reducing crime. 3) Income does not correlate with crime so social welfare giveaways are irrelevant (they don’t work anyway). 4) Nothing suggests that gun control is relevant to the issue of crime.
Is gun control possible in the United States? Maybe over a century. There are so many guns the issue deals with an impossibility.
I had a wife who was an extreme Lefty lawyer and a major force in prison reform. She always said: 'The second amendment is very clear English. If you don't like it, change it.'
Nobody is likely to change the 2nd amendment in our lifetime. It requires 3/4ths of the states to ratify a new amendment.
The Supreme Court for the first time took up the issue in a Washington DC case in 2008 and ruled on the 2nd amendment as a core right. We are now on track for the courts to allow virtually unlimited possesion of guns by private individuals. Some registration, training and limitation on types of arms may be constitutional.
What more is there to say about gun control? I can't see how this will impact, open-carry or concealment. Some states will have it others won't.
Measurements have not been reliable on punishment enhancements for crimes with guns, but I suspect they work and could be refined. Punishment enhancements are irrelevant to mass killings which are a subset of crimes of passion.
