This is interesting. The cop that shot Taylor was apparently a new resident in the neighborhood and was helping another relative move in across the street.
While the wife who was not outside at the start of the incident claims there was no controversy outside over a parking space (see links in OP's original link), at least one bystander reported this to be the case. http://www.upi.com/Top_News/US/2011/...4031303817395/
And check the videos in this link ^. The witness noticed the disturbance. Also notice that the girlfriend who claims that Taylor did not wrong was nowhere near around at the start of the incident.
