Using Enron to explain Bedford’s law of forensics statistics

Some frauds are sometimes easier to uncover. For example, in a recent Iranian presidential election, the governing candidate led by 2 to 1 votes all night. Next to no variation despite returns coming in from the more liberal cities and the rather conservative country ballot boxes.
Bedford’s law is used to uncover fraud through peculiarity in the occurrence of numbers. The law states that in many naturally occurring collections of numbers, the small digits occur disproportionately often as leading significant digits such as the number one.
In the finest traditions of Stephen Stigler’s law of scientific epiphany, Benford was the second person to discover it and he got credit for it rather than the first (Simon Newcomb) by undertaking a proper analysis:
Newcomb didn’t provide any sort of explanation for his finding. He noted it as a curiosity, and in the face of a general lack of interest it was quickly forgotten.
That was until 1938, when Frank Benford, a physicist at the general electric company, noticed the same pattern. Fascinated by this discovery, Benford set out to see exactly how well numbers from the real world corresponded to the law. He collected an enormous set of data including baseball statistics, areas of river catchments, and the addresses of the first 342 people listed in the book American Men of Science.
Benford observed that even using such a menagerie of data, the numbers were a good approximation to the law that Newcomb had discovered half a century before.
About 30% began with 1, 18% with 2 and so on. His analysis was evidence for the existence of the law, but Benford, also, was unable to explain quite why this should be so.
If someone tries to falsify numbers, they will have to invent some data. They use too many numbers starting with digits in the mid range, 5,6,7 and not enough numbers starting with 1. This violation of Bedford’s Law, suggesting the possibility such as at Enron.

How to make the case for arming British police when attacking American police shootings

More British English, Scottish and Welsh police (68) have been murdered by gunfire than British police have shot people dead (52) in over a century.
Source: Number of police officers shot dead in the UK by decade | John Graham-Cumming.
This suggests to me that the ledger is in the wrong direction. This list does not include British police stabbed or beaten to death nor are Northern Ireland deaths.
According to the FBI, from 1980–2014, an average of 55 law enforcement officers are feloniously killed per year in the USA. Those killed in accidents in the line of duty are not included in this number.
More law enforcement officers are murdered every year in the USA than ever murdered by gunfire in Britain. Police have the same common law right as any other to defend their own lives and the lives of others.

Personal cameras as evidence that criminal deterrence works and works well

Hutt City Council parking wardens are the latest in a long line of frontline staff to wear lapel cameras to deter assaults and verbal abuse. These lapel cameras are another illustration about how criminals and miscreants respond to incentives and are deterred by a greater prospect of being caught, convicted and punished. In the case of lapel cameras, there is a greater prospect of been identified and recorded for later proceedings.
The introduction of personal cameras in New Zealand prisons in high risk areas lead to a large reduction in the number of incidents of violence and abuse towards prison staff. Chief custodial officer Neil Beales said:
The use of on body cameras has led to a 15 to 20 per cent reduction in disruptive incidents (which can range from very minor to more serious) in units where cameras were used, compared with units where they were not used.
Even hardened prison inmates respond to incentives and a greater prospect of being caught and punished.
The introduction of personal cameras is not a priority for the New Zealand police. Mention was made of a six year long budget freeze as one of the reasons.
The first randomized controlled trial of police body cameras in the USA showed that cameras sharply reduce the use of force by police and the number of citizen complaints.
In Seattle, where a dozen officers started wearing body cameras in a pilot program in December, the police department has set up its own YouTube channel, broadcasting a stream of blurred images to protect privacy.
