We'll find out Tuesday, when the LA County Health Dept is required to present any such scientific studies/evidence in court to defend the restriction on outdoor dining.

(While Newsom has issued a statewide order that would theoretically lockdown all of SoCal and moot the county order, he doesn't actually have the authority to enforce those restrictions; that is handled at the county or city level by local law enforcement, nearly all of which have said they will not...even in Sacramento. Notably, even in CA local law enforcement for the most part has refused to enforce the lockdowns imposed by their own local governments.)

This is really not just about outdoor dining. Here, they are comparing outdoor dining that is open against outdoor dining that is closed. We already know the circumstances of how they operate and the precautions they are taking are likely not equal.
