They might as well pass it, but it's not going to help much
Support for state crisis intervention
I have no idea what that means. It sounds sorta like "The next time somebody makes a threat we'll do something about it, until we realize that the Internet is full of death threats and we're going t ignore all of them."
Investment in children and family mental health services
Good, but it's not going to prevent mass shootings.
Protections for victims of domestic violence
Again, good, but not going to prevent mass shootings.
Funding for school-based mental health and supportive services
Again, that's good, but it's nowhere near enough to help out the kind of seriously disturbed people at issue here.
Funding for school safety resources
This is going to be worse than useless. This is security theater.
Clarification of definition of federally licensed firearms dealer
I didn't realize that this was an issue. Congrats on closing some sort of loophole, but there are plenty of ways to get a gun.
Telehealth investments
Yay, but what does that have to do with anything?
Penalties for straw purchasing
Something that should have been done a long time ago, but it's not even a band-aid.
All in all, this is one of those situations where doing anything is impossibly hard. They got 10 Republicans, the minimum number to do anything at all -- and it's doing barely better than nothing.
Even at that, I'd give at least even odds that this fails to pass. It requires every single one of the 50 Democrats to agree to it. Any of them could object for any reason -- perhaps they don't like the way it stigmatizes mental health, or perhaps they think that "state crisis intervention" could be used to harass gun owners. There is no room to negotiate about it, since any change will alienate somebody who hammered out this compromise in the first place.
