Every one of these is a worthy goal. But so too is building a lot of affordable housing quickly and cheaply. Los Angeles is failing, and failing badly, at doing that. Given that failure, does it make sense to be asking for special air filtration systems for developments near freeways when the alternative, for many of the would-be residents, is a tent beneath the freeway? To pose the question sounds callous. But to refuse to pose the question, given the need for more housing, is cruel.
