Four sensible gun laws that would have an effect

Scientific American published an article that research shows actually reduces gun violence.  Here is a summary of the article:

1. Require permits to purchase - rather than background checks, which are done by sellers and aren't really complied with, this would require in person applications for a permit with local law enforcement.  10 states do this and it resulted in a 68% reduced risk of guns being diverted to criminals.
2. Ban individuals convicted of any violent crime from gun purchase.  Not just domestic abuse convictions, but all violent crime convictions would ban you from buying guns for life.
3. Make all serious domestic violence offenders surrender firearms.  Apparently, the current law only asks offenders to voluntarily surrender their guns.  A study showed that relinquishment laws are 50% more effective than non-relinquishment laws.  Tempers flare in domestic situations, and if guns are available...
4. Temporarily ban active alcohol abusers from firearms.  Research says that DUI offenders are 4 - 5 times more likely to violent crime than those with no criminal record.  The suggestion is no guns allowed for those with two or more DUIs in the last five years.

These are specific and targeted gun laws that would focus on high risk gun buyers and be of no threat to Second Amendment advocates who are afraid that a tyrannical government is out to confiscate their guns and establish a totalitarian police state.

I think these are well thought out.  Too bad they won't be considered by the NRA and their Republicans elected officials afraid of NRA condemnation.
