that’s a period after the 30, not a comma.

Terrific observation. Most people when they write “30”, they often place a period and 3 zeroes after. We’ll just disregard that the story specifically stated 30,000 were trapped.

Still, this obvious typo is so egregious that it needed several posts to talk about it. Thank you for being you.

Europeans use a period where we would use a comma as a separator
