GPS jammers illegality

In connection with the consolidation of GPS positions due to expanding the scope of its application, recently the U. S. Security services set the goal of combating with the proliferation of GPS jammers (devices that interrupt the work of GPS-receivers) for the control of various services. Such idea seemed to be superior persuading Google to terminate the on-line searching of GPS blockers, according to Bob Brewin, the lead developer of nextgov.com, this idea worked at least for some time.
On April, 7 a main designer, who had been writing about the GNSS problems for many years, was amazed with the number of links in his blog, which Google showed on request "GPS jammer" (GPS jamming signal). Brewin immediately got into touch with the guys from Google. They informed that "The GPS-jammers’ references are in contrast to the company policy, which bans advertising of hacking and some related technology", and that they will remove the problem. Indeed, the search on request "GPS jammer" have no effect in the evening. But on request "GPS jammer" with note "Shopping" Google found 3 ad links on the GPS-jammers’ sites.
And there was a great quantity of pages about such blockers in other search engines. In Feb, during the conference British expert David Last said how he reached 185,000 references on that request. The amount of GPS-disablers’ sites increased by 50% just in a month. The abridgement of search of the exact phrase "gps jammer" by Google will take away approximately 106000 links – but it is a small relief.
