Hard Numbers: China hits zero, Iran prisoner pardon, Americans on the brink, and Mexican justice

10,000: Iran's supreme leader will pardon 10,000 prisoners, including political ones arrested during anti-government rallies, as a goodwill gesture in honor of Iran's Nowruz New Year. That's on top of the 85,000 prisoners the government recently released to stem the spread of the coronavirus.

29: Our nerves are shot right now, and many Americans believe the end is near. A YouGov survey conducted in late February found that 29 percent of American adults believe there will be an apocalyptic disaster in their lifetime. Some 17 percent say they have an apocalyptic plan in place for their families. Phew!

43: A Mexican judge has issued an arrest warrant for a senior official at the Attorney General's office who oversaw the infamous case of 43 college students who disappeared in 2014. The judicial pursuit of the high-level official believed to have participated in the gruesome crimes (and who is now on the run) is a big deal considering that over 90 percent of all crimes in Mexico go unpunished.

0: As much of the world is battling the coronavirus outbreak, China reached a significant milestone Thursday. Granted Chinese statistics aren't always reliable, the government reported no new locally transmitted infections for the first time. But many worry about what would happen if a second wave hits China, because many of the rigorous measures implemented by Beijing to curb the disease's spread aren't sustainable in the long term.
