They have a law to enforce. The law enforcement activity is as good as the law :(
within the US context, the government isnt allowed to just have any law it wants, and it isnt allowed yo enforce laws that breach individual rights
"I was just enforcing the law" is no better than "I was just following orders".
Every minute spent tracking down a lady getting an abortion is a minute not spent tracking down a murderer or a rapist or similar.
