Cop #1 Lets send a text to all these cell phones to find the murderer.
Cop #2 How will that work?
Cop #1 The cell phone that is shut off is the murderer.
Cop #2 But won't the murderer know we would think that?
Cop #1 Yes he would, but since we didn't catch the murderer in the act they must be intelligent so they would know we would think that.
Cop #2 Oh, so they will not shut their phone off?
Cop #1 Correct. Except being a murderer they won't trust anyone so they will suspect that we will be setting a trap with the texts and will be afraid to receive the text. So the will Shut their phone off.
My parents refused to pay for television and I inherited that from them.
I recently moved and I am now a Comcast subscriber.
BUT I have their teleworker internet only. I pay $39 a month for internet that is 4 times faster than my previous century link that cost more. $39 includes their modem and because it is "business class" they are no additional fees and if it is out for more than 30 minutes they owe me money under the SLA.
