2015: American police killed more people in March (111) than the entire UK police have killed since 1900

A total of 111 people were killed by police in the United States in March of 2015. Since 1900, in the entire United Kingdom, 52 people have been killed by police. Don't bother adjusting for population differences, or poverty, or mental illness, or anything else. The sheer fact that American police kill TWICE as many people per month as police have killed in the modern history of the United Kingdom is sick, preposterous, and alarming.
What a worrisome statistic!
