To better define the situation/risk levels, an analysis of the outcomes of four LEOs not going into a surprise situation vs. one BLM, ranked by priors and possession of a Gun BURGLARY Loophole firearm, on drugs would likely give a better set of statistics.
The post at #58 was what I was driving at. As I implied at the end, if there are factors like those you and I pointed out, the risk is probably much greater, and even a police officer like this one who shot the man, perhaps even with her limited experience, could sense all too well the danger inherent in the situation with all those other things rolled in.
