On a more serious note, consider the concentration in the Great Lakes area. I know there is an annual walk across the bridge up in Michigan that involves many thousands of people on September 4th. This is something that law enforcement authorities ought to take note of. Perhaps they are planning on taking the bridge down with cellphone bombs.
I'm glad you added that. On another thread they said 65,000 people walk across that bridge every Labor Day weekend.
I think I am going to avoid any large gatherings in the near future.
How many per bridge? How many bridges, counting NY, SF?
How many per dam? How many dams in 48 states?
How many per mall? How many malls in 50 states?
Could they be planning something to concentrate on multiple attacks and targets, using thousands of cell phones bought from all over the country?
Do the tracphones expire if not used or activated in a certain timeframe? If not maybe they should.
