If the expectation is that the cops will come in with weapons drawn any time they execute a warrant then we have to realize that this will result in people accidentally being killed. Does the standard for evidence for obtaining a search warrant justify the increased risk of someone innocent dying?
Some people would argue that not having guns drawn in this type of case would result in more police deaths. I agree but don't view this as a deal breaker. How many civilians will die with guns drawn vs how many police officers die without? Should we count civilian and police lives the same in this situation? Police officers are compensated for the risks they take and have protective gear like body armour to reduce this risk. In the linked video I don't see the police using any head covering other than ball caps. If they thought there was a risk why didn't they put on helmets? I'm sure the Tallahassee police have access to that kind of PPE. The fact that they chose not to wear full PPE suggests to me that they didn't believe there was a substantial threat in the home.
If she was compliant, they would typically ask everyone to exit the house before they enter to clear it. This scenario specifically took a different approach. I don't see a higher risk of innocent people being killed, so maybe you can gather some statistics on that since the scenario is really a counter example to that.
Every building search is considered high risk. It's not an extreme risk, which is why they didn't execute it as a no-knock with SWAT, but there is still risk. The actions taken appear to consistent with that level of risk.
This link [0] shows that US police kill over three times as many people, per capita, than Canadian police. However, I think there are other issues, like easy access to guns, that affect this stat so this isn't really a very useful stat for our discussion.
This group [1] has been collecting info on arrest related deaths but a quick look only showed me links to how they collect data and not the actual data. It also looks like they stopped their surveys in 2012.
This paper [2] has some of the most relevant stats I've found for our discussion and covers use of lethal force by police between 2009-2012. From their numbers, 83% of victims were armed or believed to be armed (this includes toy guns, etc) and over 93% of the deaths were from firearms. If we assume that the 7% of deaths were the police didn't shoot all apply to unarmed victims then 10% of the people killed by police were unarmed and shot. Their stats also show LEOs being killed in less than 2% of these incidents. Their numbers do show 9% of these cases resulting in an injury to LEOs but we don't have numbers on non-fatal police caused injuries so I don't want to compare apples to oranges.
I think I remember this paper from a while back, but read it based on a different perspective (ethnicity).
Unarmed in the context of this paper would only be as it applies to deadly weapons. The suspect could still pose a threat with an alternative weapon (such as a pipe) or even pose a threat with bare hands too. The percent of people killed without posing an immediate threat would be more appropriate, and was 5% (would like to see the details of those with prosecution metrics). I would guess that 5% that mostly fits in the 7% you mentioned (which includes cars, suffocation, falls, etc), but unfortunately the paper doesn't seem to get granular enough for that. So I don't think we can draw a good conclusion from this paper that there were more civilians unjustly shot by police than the police being shot by civilians (the paper leaves out non-fatal incidents too). On that note too, the 2% officer fatality rate you show would not be fully encompassing. Meaning, it would be missing encounters in which the suspect killed the officer without also being killed.
