Guns are deadly weapons; cars can be too. We should, at the very least, require the creation of gun license,registration and insurance equivalencies to the existing motor vehicle registration and driver's licenses, with proficiency & eligibility testing on the same level, i.e. yearly renewal, etc.
Why is this important?
We are all personally affected by the incredible growing number of shooting deaths, which are cropping up in places that would never have been imaginable a decade or two ago: schools, movie theaters, churches, concert venues and more. Gun owners have not been able to "police" their own kind, but push for unregulated ownership. The days for that should have been gone long ago. We don't hear car companies and auto associations ranting about the government taking away our "rights" to cars, why shouldn't the same types of ownership hurdles and proofs of responsibility not be applied to firearm ownership? We don't want to abolish the 2nd amendment, but dangerous things need to have restrictions placed on them until you can prove yourself and earn the responsibility. That includes stricter age limitations, "learner's permits" restricted to less powerful weapons, psychological testing to prove you have a stable personality and are not intending to use them on other people due to depression or mental illness, etc.
