Yeah but they would have to completely regroup and probably wouldn't have time to do what they planned.

"Yeah but they would have to completely regroup and probably wouldn't have time to do what they planned."

That's true. For this time around. But banning pre-paid cellphones will just mean that they will find another transmitter source to use next time.

I'm a Amateur Radio operator (HAM) and I could build a transmitter small enough to fit inside a pen.

Would it be powerful? Of course not, but then it doesn't have to be to send a signal a block or two away.

Are they that smart of sophisticated enough to build their own? Doubtful, but possible.
