I'm of similar mindset.
Go ahead. Ban semi auto assault and other guns. It's ok with me cause I know the laws on paper are going to protect me. I also expect the police to destroy all such weapons in their possession as well, after all, they won't need them anymore because the world will be a safe place thanks to the new laws! I'm sure the criminals will hand over all such weapons when the law hits the paper! No need for cops or le of any kind to have those weapons because the law will clearly stop criminals , the criminals will stop and think real hard, " hmmm, I would do this, but it's against the law, better not"
Then we can all eat rainbow stew with a silver spoon underneath skies of blue, drinking that free bubble up!
