Except for the "idiot" part, that is in fact what all the extant research and experience tells us. There's no evidence any extant or proposed gun control law meaningfully impacts criminal access, they merely inconvenience the law-abiding. Similarly, the majority of firearm suicides in this country involve adult, male gun owners. They already have free access to the means to kill themselves if they so choose. No safe storage or other law can prevent them, and suicide is a job for psychologists, not general gun restrictions. Rates of accidental harm continue to drop.

We don't have a "gun violence" problem per se in this country, we have a persistent and very small sub-culture of violence causing most of the harm.  What the Chicago PD Superintendent said, and any law enforcement officer being honest will tell you, is law enforcement resources need to be focused on those known players and, when caught, they need to be given stringent sentences, not repeatedly pleaded down and released.
