As is suggested by others, laws and regulations are for the law abiding... Put the onus on the law breakers and make the penalties such that any mentally competent person will recognize the error of their ways... if they are not mentally competent, sorry. For example: Commit a crime with a firearm...minimum 5 years; discharge a firearm during the commission of a crime...minimum 10 years; kill someone during the commission of a crime...mandantory life; kill multiple people or first responder during the commission of a crime...the big needle. No pleas, no deals. There is no excuse nor rational explanation for the action of wackos that are making news today. Looking at the number of weapons held by law abiding citizens of the USA (300 million or more), compared to the number of (non suicide) deaths attributed to all firearms (5k or so), it is very clear that law abiding firearm owners rank very high on the responsibility scale.
