It was not the case. We were already after the vigil so we put our banners back into our bags, we were wearing scarves of the type many women wear everyday and our ARCWP women priests put their stoles into their bags too. I remember they were ready to give back the albas (although with some degree of hesitance) to the police as well but the police said they could have them (even if told these were albas) and the Vatican's gendarmerie didn't recognize it as albas. There was simply no reason for such reaction. By the way they still kept an eye on us so they could immediately react if we did something inappropriate. But we prayed peacefully with other pilgrims.
