anchor text: Personal theft
I really don’t equate “bicycle theft” with an act of terrorism. Inconvenient yes, terrorism no.
Unless you are getting money from the U.S. Department of Homeland Security of course. They fund studies of how to hide power transmission stations that are too large and dependent on air cooling to be enclosed.
I guess putting blank spots on maps would only serve to highlight their presence. DHS could ban the manufacture of printed maps. Only allow electronic ones. Which can be distorted to show or conceal whatever the flavor of terrorism is for the week.
It would not take long for the only content of the map to be “You are here.” With no markers as to where “here” might be. But then you are there so look around.
