In New York State, lawmakers in 2021 limited solitary confinement to no more than 15 consecutive days.
The bill would ban the practice beyond a four-hour “de-escalation” period during an emergency.
I don’t know enough about prisons or psychiatry to say whether 15 days is too long, but four hours seems like a rather short time. People who aren’t in prison routinely spend more time than that alone as part of a normal day.
