Ahhh, I love all the armchair, hindsight commandos who can tell the HRT and SWAT just exactly how wrong they were, and how they should have done it.
Right. Thanks for the input, Dilbert.
Of course it seems like overkill in hindsight, just one guy (kid, really), with what seems to have only been a handgun.
But that's completely discounting the bigger picture, not just the attack on the marathon, they:
--Carjacked a civilian at gunpoint
--Murdered a police officer in cold blood sitting in his car
--Led police on a brief chase, specifically STOPPED the car to begin firing on police
--Seriously injured another
--Were throwing explosive devices, which the cops had no way of knowing how many, how elaborate, or how powerful they were
--Has explosive devices on his body
--Unknown whether there are deeper links/training from real terrorist orginizations, and how well they may have been trained
--Kid deliberately runs over his own brother in attempt to get away
--Even when cornered and badly injured, returns fire
...all on top of the fact that they kinda maimed 150+ people 3 days before.
Bottom line: what really complicated things, obviously, was the presence of explosives. This wasn't just some random carjacker on the loose with a Glock. Nobody knew exactly how many or what kind of explosives this kid had, but it was obvious he had no qualms using them and killing people with them.
