I've heard different interpretations of Governor Newsom's order in CA re staying at home. This is the order -
Order.
As I read the Order, there are numerous exceptions to having to stay at home - almost to the point of making the Order useless. The Order requires "all individuals living in the State of California to stay home or at their place of residence except as needed to maintain continuity of operations of the federal critical infrastructure sectors, as outlined at https://www.cisa.gov/identifying-critical-infrastructure-during-covid-19."
The "federal critical infrastructures" are listed here -
Federal Critical Infrastructures. The list includes 16 sectors, which can be further broken down into subsectors. Just one example of how the Order doesn't align with the public perception of the Order is this: One of the 16 sectors is the Commercial Facilities Sector -
Commercial Facilities Sector. This sector includes casinos, hotels, amusement parks, office buildings, malls, sports venues, and other areas which, of course, are closed and should be closed. But, according to the Order, citizens are permitted to leave their home to ensure the continued operation of these facilities.
In short, the spirit of the Order (to stay at home unless necessary to leave), is different than the express terms of the Order. Under the express terms of the Order, it appears that numerous exceptions are there for people to leave there homes. For example, the LA Times reports that the operation of marijuana dispensaries is an "essential service" that can remain open despite the Order -
