The presumption in that question is that…he was going to McDonald's for milkshakes every Friday night and we could have just picked him up in a taxicab. These people deliberately try to evade capture, and putting yourself in a position where you can properly ID and move against them takes a lot of planning. I don't think anybody's going to apologize for the effort over such a long period of time that eventually led to his capture.
