Sunday assorted links
1. Emily Owens survey on the economics of policing. Or try this link.
2. Europe’s reopenings have mostly gone OK.
3. Give masks to people held in custody.
4. New policing bill introduced (NYT, seems mostly good).
5. Is cell-mediated immunity relevant? Important if true, speculative, but to my amateur mind increasingly not crazy. It is lacking in sufficient direct support to say “I believe it,” and needs to be tested against concrete alternatives at more micro levels, and it has some uncomfortable “residual” properties (hi Bob!), but so far it is the only theory that fits the data and surely that is worth something.
