Actually violence is more related to the age distribution of the society than mass media. The most violent group tends to be late teen to early twenty males. This can be worsened by local norms that glorify violence.
One reason for the overall drop in violence is the aging of Western countries.
When one ships by a truck the paper work includes a description of the shipment on the bill of lading. But when using a courier or package service the paperwork does not require a description of the shipment on the waybill only addresses for domestic shipments.
International shipments will have customs declarations that describe the goods and their value so the correct duty can be assigned.
So if the shipments are coming from Canada or Mexico the area to look at is the customs declarations. If they are incorrect then the shipper/receiver can be hit with try to evading paying the proper duties. If the shipment is domestic there is currently no method to determine what is the contents are.
MS' strategy has the potential of backfiring because there is enough IT talent available in most countries to rewrite the derived applications for another base application or OS.
Munich apparently got fed up with the money grubbing antics of MS and the cities lack of overall control that they went completely FOSS. Munich has their own city developed Linux distro - LiMux (I believe it is an Ubuntu derivative).
Any method that relies on the skill of the analyst is error prone. While most of the errors are innocent, this allows for the abuse of the system by those so inclined. Combine this with the fact most lawyers and judges aka shysters are not trained scientist and tend to be dazzled by the best bs'er. The recipe is for a system that looks scientifically object but is very subjective because of the high error rate.
The complaining authors are direct suppliers to their publisher not Amazon (or any other retailer). They are supporting their direct customer but are losing sight that their direct customer ultimately makes money when their indirect customer (Amazon) sells a book to even more indirect customer - the reader. Amazon, like any well run retailer, is paying attention their direct customer; the consumers. Amazon knows that for everyone to make money someone must ultimately purchase the product; this fact has been ignored by the authors.
Another point, in most genres, the publisher is not that important to most readers but the author is. People buy books written by JK Rowling, James Patterson, Steven King, etc. not published by HarperCollins, Penguin, Amazon, etc.
The Toronto mayor does drugs and is apparently an amiable, relatively harmless loon. The Peoria dimbulb is petty tyrant (pick your favorite tyrant if you want a name), drunk on his perceived power and thus much more dangerous.
Every device I have seen has a default password to allow the initial setup of the device. Some enforce changing the default password to something else during the initial setup. Even if they do not require changing the defaults one should as a matter of good practice. Some of the blame goes to whoever "installed" the equipment and failed to reset the passwords.
Another reason the Internet lessens the impact of serial killers or stories like this is most people are not interested in them. On the Internet one can follow news topics of personal and professional interest in more depth than the regular media normally does.
Most of the publicity about crime stories is media hype. Rarely do the stories impact the viewers/readers lives in any meaningful way. To pick a city, Chicago, just about any murder in Chicago will likely have no affect on me - I do not live in the Chicago area. But if there is a murder that the media latches onto I will know more about it than I really care or need to know.
