Weird how the internet can tell me 1.6 million people died in gulags but there is no hazy estimate of how many folks have died in US prisons other than a report for 2001-2014 which hilariously misorders cause of death to downplay homicide and 'missing'.
I think the statistic you might have seen is around 30% of Americans have a criminal record, i.e., been arrested and convicted of a crime.
This is the meme I was thinking of. I had the numbers close, but the overall idea incorrect:
