Whatever your concerns about the contemporary Phoenix police department, it was still very interesting to learn about their history. From the brutal Wild West "jail rock" where prisoners were originally chained to await trial before the jail house was built (and often perished under the hot Arizona sun) to the first women on the force, there was a lot to see and consider. Not as brilliant or extensive a collection as the Vancouver BC Police Museum, but this one is donation-only. The retired police officer working the desk was also very friendly.
