Posing as clergy.
Back in the 70’s a policewoman nicknamed “Muggable Mary” would disguise herself as a homeless “bag lady”, prostitute, drug addict, etc to lure criminals. She actually scored a lot of arrests and became one of the most decorated women in the NYPD for her efforts. Yet true to form, the ACLU attempted to obtain a court injunction forbidding this practice on the grounds that “a mugger should know who he’s mugging”.
