Was there anyone hysterical over that? They prevented him from easily fleeing. I mean they had a dead police officer and a shootout where multiple very loud bombs went off.
Worse crimes happen with some frequency yet the response is never nearly that large. Boston is the only time I have ever heard of an entire major American city being shut down on order to chase a single criminal. His crime was not exceptional, aside from the "terrorism" angle. Such a massive overreaction is hysteria.
Worse crimes than injuring 246 people and killing 5? The only reason it might not be "exception" is the number of heroes that prevented victims from bleeding out. Without immediate aid, nearly everyone that lost a limb would be on the deceased list.
