Walking home tonight, I saw someone force open a locked fence and start trying doors in the yard of an auto repair shop. I called 911. Having described the incident and location, the first follow up question I was asked was, "what was his race?" When I was unwilling to ascribe an ethnicity to the offender based on a quick glance I got at a guy in a hoodie with terrible lighting, the response I received was "we'll alert the nearest officer" and a hang up. I want to follow this up. Best course of action?
