>PRESIDENT BARACK OBAMA: If, technologically, it is possible to make an impenetrable device or system where the encryption is so strong that there's no key - there's no door at all - then how do we apprehend the child pornographer? How do we solve or disrupt a terrorist plot? It's so disappointing to me to hear a quote like that from the President.
So how DO you disrupt criminal plots, then? Do you allow people to conspire to commit crimes? You're going to find, that once you think it through, that you'll end up limiting the rights and freedoms of individuals... there's no getting around that. Life sucks that way. People were never their own little countries. I just feel sorry for the middle-class suckers that thought they had freedom. Poor guys - they never fi…
From that, there is also meta studies/books that has asked what the studies has shown. To take an example, the book freakonomics pointed out that out of all the crime reducing strategies, abortion laws has shown to be one of the best method. Unwanted children tend to have higher risk of being born with low social and economic status, which is then a strong predictor for crime. None of the other strategies that were looked on had any major effect on crime rate.
Then we have surveillance. Government studies has shown CCTV is effective to reduce vehicle crimes, but no evidence is found that it prevent violent crime. One study concluded that better illumination could be a cheap way of cutting illegal activity to the same degree as CCTVs.
Surveillance in stores and bank has shown a very unexpected result. It has proven useless in preventing robberies, and shoplifters are generally not bothered by them. However, studies has shown that employees accounts for 43% loss of revenue from shoplifting and that is reduced by surveilling. Banks was also one of the early adapters who noticed this.
Then we have studies such as the last month from Harvard, which said that the available information that police investigators has when investigate crime is increasing at a very fast rate. "The trajectory of technological development points to a future abundant in unencrypted data," the study said. Comparing today with the days before encryption, and today is much easier time for a police investigator.
