Why couldn't they go in through a window? Why not breach the door with battering rams? How much backup do multiple cops armed with handguns need against one guy

Why couldn't they go in through a window? Why not breach the door with battering rams? How much backup do multiple cops armed with handguns need against one guy with a rifle? Being outgunned is not an excuse. They signed up for a dangerous job (isn't that the justification we hear all the time when discussing wrongful police shootings?), and they ought to do it when called upon, even at grave personal risk. Charge the gunman with bare hands if you need to. It's easy for me to say because I don't think I'd ever do it. But that's also why I would never try to become a cop.
