I can't believe people are using this situation to claim that Boston somehow botched this job up. JFC.
Most manhunts take years to find the right guy. This was a situation where two guys dropped bombs in public with no cops or security to see it. They identified the suspect, tracked them down, and either captured or killed them in a few days. It was a tremendous collaboration between the city, the police department, the businesses in the area, and citizens.
Drop your agendas for 5 minutes, please. The idea that Boston and Boston PD should get no credit for tracking the guy down just because they were tipped off by someone is just plain ludicrous.
