They definitely will not do so against the particular kind of shitbag that wants to mass murder queer and trans people.
The police are a brutally far-right institution themselves and they enforce (or ignore) laws accordingly. Given that reality harsher gun control just disarms communities under attack.
Contrary to popular belief the u.s. is not and has never been a place where just anyone can go around armed. The point, from colonial times, is for a heavily-armed conservative elite with others largely disarmed. It ain't coincidence gun laws have staggering racial disparities in enforcement.
I wrote about this awhile back, but it's definitely worth a reminder now.
