posted about a sign in the UK that asks "What if someone with several (mobile phones) seems suspicious?" (Click on the image to the right to see the sign larger.) The paragraph then reads:
Terrorists need communication. They often collect and use many anonymous pay-as-you-go phones, as well as swapping SIM cards and handsets. If you're suspicious of the number of phones someone has, we need to know. Let experienced officers decide what action to take.
On one level, I do understand the point they are trying to make. But on another level, I just think of all the people I know who travel to trade shows and conferences with a whole range of cell phones!
