So 104 people were killed by police in the USA during August, 2014. To my eyes, that's an absolutely enormous figure. As a Brit, I compare it to the 1 person killed over 3 years by the UK police. Yes, they're two different countries, yes there's a lot more people in the US, yes they have different cultures, yadda yadda yadda; people are dying here.
Let's do some maths:
- Population of the USA: 319 million (source: http://tinyurl.com/bpotuf9)
- Percentage chance for a person to be shot in August is then: (104 x 100%) / 319,000,000 = 0.000033%
That's a scarily huge percentage, given that it's normalised by population. Bear in mind that police in the USA are not ... shy ... at shooting at suspects, and neither are they 100% accurate. Some of the casualties are in fact bystanders.
Now let's consider extrapolating for the period of time that most shootings occur (i.e.: suspect between the ages of 15 and 40), and see how that changes things:
- Chance to be shot over 25 year period = (104 x 12 x 25 x 100%) / 319,000,000 = 0.0097%
- Rounding that, since this is an extrapolation, we get 0.01%
Now that's an amazingly large percentage chance of being shot dead by a policeman. Let's do the same thing for the UK:
- Population of the UK: 65 million (source: http://tinyurl.com/kzsalbe)
- Percentage chance for a person to be shot over last 3 years is then: (1 x 100%) / 65,000,000 = 0.0000015%
- Therefore percentage chance for a person to be shot in August 2014 is 0.0000015 / 12 / 3 = 0.0000000427%
- Therefore percentage chance to be shot over 25 year period is 0.0000000427 x 12 x 25 = 0.0000128%
Compare 0.01% and 0.00001% and remember these are normalised by population. Yeah.
