If the shutting down of cell phone signals deliberately is even possible, then it would be smart to do this in order to keep terrorists from communicating with one another in order to do coordinated attacks.
I find it interesting that I was hundreds of miles to the south at a Big 12 football game and was unable to use my phone (svc unavailable) from about 7:30 p.m. to about 8 p.m.
See post #895.
its congestion. there is no way the government authorities could organize such a logistical effort to turn off cell phones so quickly after an unexplained bomb goes off in Oklahoma. and why turn the service back on at 8PM? was the crisis over by then, had every stadium been searched for bombs by 8PM so as to safely allow the cell phone service back on? no way.
If you were at UT, it's not suprising the cell phones would not work. I attended the UT NU game a couple of years ago and it took me many tries to get out. I've also had trouble just driving by on I-35 when there was game at UT, all the way from about the south 290 intersection to the 183 split on the north.
