Yes, you read it right. The Sac Bee reports:
At least 148 women received tubal ligations in violation of prison rules during those five years – and there are perhaps 100 more dating back to the late 1990s, according to state documents and interviews.
From 1997 to 2010, the state paid doctors $147,460 to perform the procedure, according to a database of contracted medical services for state prisoners.
The women were signed up for the surgery while they were pregnant and housed at either the California Institution for Women in Corona or Valley State Prison for Women in Chowchilla, which is now a men’s prison.
As you’ll see in the piece, the issue of consent is contested.
