I guess there are stories of all kinds concerning this issue. A small group of volunteers from my parish weekly went to the local jail to offer a Bible Study, and the leader took Rosaries to give away. He has great devotion to Mary, and was seeking ways to call others into devotion to her. The Rosaries were very inexpensive, plastic and multi-colored. A few weeks after this began, the authorities there forbade any distribution of Rosaries and the wearing of them outwardly - the different colored Rosaries were being worn and used as Gang “colors”, to define who was a member of which gang in lockup. And to wear the colors of a gang to which one did not belong was very seriously “not good”.
If I remember correctly, any Rosaries since were confiscated. All gang identifiers are very problematic around gang cultures.
