Perhaps we can solve a few problems. Banning guns is definitely unconstitutional. The Second Amendment was written to protect citizens from a tyrannical government, which is nearing.
Does anybody blame the car when a homicidal individual blows himself up in a car bomb? Since there is a Sky Marshall Agency, consider that the U.S. create a School Marshal Agency. The Israelis have been doing this for years, so we do not have to reinvent the wheel. This group would be comprised mostly of veterans, returning from spending decades guarding third world countries, that can’t find jobs. They are physically fit, trained in weaponry, security, surveillance, devotion to duty/mission and most important willingness to react in a stressful situation and they need good jobs. They should be dressed appropriately and discreet. Very adequately armed but concealed.
I believe there are enough unemployed vets wiling to secure the schools and relieve an overstretched police force. Then schools will not be gun free zones as are they are now and vets will have job placement. If you notice you have never heard of one of these so called unstable murdering cowards attacking a police station, military base, or biker bar - they are stable enough to know better than to try those locations.
The agency should not be attached to the TSA or Homeland security and not an active military unit. Completely civilian perhaps F.B.I., U.S. Marshals or even a new separate agency. But most important it should not be administered by bureaucrats lacking military background experience.
While we are at it lets take some funding from foreign aid and return it to the Mental Health Community to contain and assist these troubled individuals instead of putting them and the general population at risk.
My greatest sympathy to those who lost loved ones in this tragedy but caution, it’s time to be proactive and not reactive to allow this administration to “never let a good crisis go to waste” (Rahm Emanuel) to their further gun control policies.
