This incident has understandably caused a firestorm. The report from CNA:  

A pro-life volunteer has been arrested and charged after silently praying outside an abortion facility in Birmingham, U.K.

Isabel Vaughan-Spruce, the director of March for Life UK, was arrested on Dec. 6 and charged on Dec. 15 with four counts of breaking a Public Space Protection Order (PSPO).

A PSPO is intended to stop antisocial behavior. Police were responding to a complaint from a member of the public who believed that Vaughan-Spruce was praying silently.

As part of her bail conditions, restrictions have been placed on her participating in public prayer. Another requirement of her bail, later dropped, banned her from contacting a local priest involved in pro-life work.

Vaughan-Spruce was carrying no placards or signs. After her arrest, she was shown pictures of herself quietly standing in the vicinity of the abortion clinic in Kings Norton, Birmingham.

She had been spotted near the clinic three times, and when asked about these occasions, she explained that she might have been praying, but she may also have been thinking about other things. Her thoughts, she explained, were all peaceful and not worthy of being criminalized.
