Peru: riot police block highway as people attempt to flee [to their home towns] amid lockdown.

Some of those people have Covid-19 and would bring it to their home towns if they go. However, the overwhelming majority do not have Covid-19, and would die if they stay in Lima. Covid-19 is going to reach those places sooner or later, but it could take time,

A better-organized and wealthier state would test them all, then quarantine those who are infected and let the rest go home. But Peru is not capable of that.

This shows us the sort of disasters that massive inequality can cause. Meanwhile, the plutocrats labor every day to make more inequality.

Proposed contact-tracing apps would do a lousy job, because what they try to do is very different from real, effective contact tracing.

Don't assume that a system, once actually in use, will respect any sort of privacy for anyone.

I hope the US does set up effective contact tracing, and if I am ever called because of a rational suspicion that I am infected and asked about my contacts, I will do my best to cooperate. If I am told I am likely to be infected, I will stay inside to protect others. But I will not use something that would let the state track my movements even if I do not become infected. I will not carry a portable phone.

To throw freedom and privacy overboard to avoid a small incremental risk to health is folly. We need to maintain our freedom and privacy along with our health.

Coal mining companies in the US are asking Congress to "rescue" them by eliminating the taxes that pay for cleaning up abandoned mines and the lungs of abandoned miners.

If coal mines are not to be cleaned up, it is better to shut them down immediately, so they stop contributing to global heating disaster.

The UK is giving patient medical records data in bulk to Palantir and other companies, for "research" purposes.

I would not trust those companies to keep the spirit of their commitments, or even the letter of them.

The US plans to test an amazing Cuban medical discovery, a vaccine which prevents one kind of lung cancer from growing any further.
