What irritates me? The police station in Sandy Hook was supposedly two miles from the school, yet it took them 20 minutes to get officers there. So what exactly were they doing, that was so pressing, it took them that long - writing parking tickets?
Police don't typically sit around the station waiting for a call. Particularly in a tiny town like that. They probably had two or three cops on duty, and they were not anywhere near the station.
The town was that small, yet it took the police that ling to get there? Newton is all of 59 square miles. What is that - about 7 miles by 8 miles? Even if they were all the way at the other end of town, they were still only 8 miles away. That's about 24mph.
