OK, let's play. https://en.wikipedia.org/wiki/List_of_killings_by_law_enforcement_officers_in_the_United_States https://en.wikipedia.org/wiki/List_of_killings_by_law_enforc... 1240 is the estimated unusually high number for 2015 and US population is just over 318 million: that's a rate of one in 256,000 (or, 4 per million). The population of Poland rose from 30 to 38m 1961-1990, so let's assume an even 30m on average for the 39 years covered by the GP. The 10-54k killed in that period come out as 256-1384 pr year, or one in 117,000 to one in 21,000 (or 8-47 per million). So, even being very generous with the numbers, communist Poland killed its citizens at a rate of twice to more than ten times the rate the US does. Including military deaths, there has been just over 100k US deaths, WWII to date, that's an average of 1430 to add to the 1240 for 2670/year, or one in 119,000 -- still (just) better than the Polish lower bound.
