There are only three streets in the complex and Zimmerman knew them well since he patrolled them nightly with his dog and his gun. Why on earth would he have to look for street signs?I have lived in my place three years and I still have to go read the street signs when I give friends directions. I walk and drive the streets everyday. I know how to get home so I don't necessarily need to know the address. I don't even know what my neighbors address is unless I go look on her door.
But Zimmerman did know the street names in his numerous previous “suspicious persons” calls to the police. Did he suddenly forget them on the night on February 26th?
