Earlier quoted context omitted.
Yes, really. The presence of vast numbers of firearms in the country isn't the relevant statistic, it's the frequency with which police face situations requiring the use of their firearm. The latter barely happens. Are US police at a relatively much higher risk of encountering an armed suspect than police in countries with less firearms? Hell yes! Is that rate of encounters "high". Nope.
It's not about whether it is "high". When you multiply the probability of the suspect shooting you by the cost of getting shot, the cost of acting nice all the time is high. Therefore, according to the statement you yourself agreed with, that cost is "relatively much higher" in the USA.
I don't think minuscule incremental improvements to officer safety justify assuming every encounter will escalate.
