I would think possiby a "police officer's uniform" that was other than DPD could have been used. That way, while "appearing to be a police officer", but not DPD, other DPD officers would not need to recognize the officer(s) in question. With all the other municipalities nearby, several uniforms to chose from. Just a supposition, but possibly a somewhat similiar situation among railroad "workers". But, somehow, it appears to me that a gunman, or gunmen, were able to escape Dealey Plaza.
