The PA state Department of Corrections sends our community work details out in clearly identified inmate uniforms for all of the reasons that you state. Fortunately, we have not had any walk-aways from these details; but if we ever did, I'd rather be looking for someone in an inmate uniform, rather than in street clothes. From a public safety perspective, I'd recommend that you keep them in uniforms. In addition, we post signs near the community work site that identifies the workers as PA DOC Inmate Work Crews.
