Setting aside my comment in the original post that the live view component of the current bill wasn't something I supported....
There's a difference between holes in the baffles and ceiling downrange and holes behind the firing line. Are the former acceptable? No. But there is a difference.
Live fire training (again, not as framed in the bill and not debating whether it should or shouldn't be mandated here) gives the new shooter a much more immediate and visceral awareness of the consequences of bad muzzle discipline. Most people never having fired a gun have no sense of how loud, how much force, how sudden and, even on a P.O.S. Glock, the difference between how much the energy of the trigger pull differs from the energy let loose from muzzle. Until somebody fires their first shot, muzzle discipline is an abstract idea. I am sure you have seen the shock almost every first time shooter has, no matter how much they may like it, the first time it goes bang in their hand.
There's also a difference between the fleeting fraction-of-a-second-flag in a crowded gun store by the experienced and trained but imperfect (or just too cavalier, or it's just impossibly crowded store environment) and the 'fresh out of the classroom, never fired a shot (at best)' new person and the sustained pointing to 'look at the sights' or 'try the slide and trigger'. What I saw, and was creeped out by, was the latter.
Even saying this, muzzle discipline is a lesson that needs drilling and, there is a difference, no matter how much we might strive for otherwise, between muzzle discipline when we've confirmed clear for ourselves and shown clear to those around us in a store or while cleaning and where there is . Do you put a chamber flag in after you've checked clear before walking down range every time? Do you re-bag the rifle? Every R.O. I've ever known sees the careful folks who might one day have the third round of a mozambique hit the target carrier trolley vs the 'no training/awareness' folks who'll turn around and point behind the line "I think it's jammed" mid string and has their attention primarily focused on the latter.
But you know all this.
