"I can't recall houses with burglar bars that didn't have them on the doors as well, and one isn't going to just break those kind in."
The cops don't break "in" the security-barred door, they rip the door out of it's casing and off the house using a hook, chain and truck.
How special. Maybe if they had been officers in uniform and in daylight, they would not be injured and she would still be alive with the front door still attached. IMHO it is police responsibilty to avoid violence even at the cost of their own lives. That means extraordinary measures, like being in full uniform and by twos for warrant service. Being unarmed would also be a plus. I have frankly had it with police activities in certain locations. There are too many in most every state in the Union.
