Do local officials actually have good evidence behind their decision to continue decreeing crippling citywide shutdowns?
After city officials’ last shutdown forced at least 132,000 Austinites out of work and into a potential new crisis, the mayor is considering doing it again.
When discussing their latest coronavirus “orders,” the officials said they wished the governor would let them fine and imprison unmasked citizens.
Local officials also instituted penalties of six months in jail and fines up to $1,000 for anyone who violates their order.
