Agreed - where are the flipping snipers with the head shot?!?!
I'm told that in real life it's not always quite so easy.
It sounds like the situation unfolded rapidly...I doubt their SWAT guys had even been activated.
It's not always possible to use snipers. If the bad guy was in a hallway inside the building, a sniper isn't practical. In addition, a lot of smaller towns and cities don't have SWAT capabiities and they may not have had time to request SWAT support from a larger agency.
