There should be areas everyone could agree. For example, this shooter registered all his weapons. Why not a flag come up and local police advised of anyone that purchased more than 4 guns in a month or 10 guns in a year. Then locals should be able to check local pharmacies for drug prescriptions and visit the individual. Why not make all firing pins degrade to useless after firing 30-50 rounds. They don't cost much and can be easily changed, but not fast enough for mass murders. I am sure there are many partial solutions others could suggest and many could agree with. But lawless politicians like the liberal Obama with the neutered power of a political opposing congress will never get me to agree to amending the 2nd Amendment to take away our weapons.
