It's obvious that US cops kill way more people than in other countries, but also that they get killed more often. They are more likely to kill because the US is designed to be a much more dangerous country than most, but also because they receive a lot less training, and training more focused on shooting, than in most countries.
If your friend dies in the line of duty their family gets significant financial support, and all it takes is a bit of paperwork no one will ever question.
That's 74 COVID deaths in the line of duty, not 74 COVID deaths for any reason. But cops are humans, if one of them dies from the third leading cause of mortality in the US our default assumption shouldn't be there's something special is going on. And they didn't do any specific testing to prove how those cops got COVID. Meanwhile your average police officer is in a higher risk group for COVID related adverse effects.
Feels a bit disingenuous when more cops died of C19 in 2022 than from gunfire - 60 deaths in 2022 compared with 74 for C19. Also US cops killed almost 1100 people in 2022 - I think they have the better side of the 18-1 ratio here.
(Also taking the first 10 as a sample - 2 were off-duty and 1 was shot by his own colleagues which isn't really "policing is risky", more "free roaming guns are generically risky".)
