Cell Phone GPS Jammer: for or Oppose

Every coin has two sides. People around the world have different opinions about cell phone GPS jammer. It’s legal in this country while illegal in another. What do you think of this kind of thing? For or oppose?

Here are some opinions from others:

A: It would be easy to be oblivious to an emergency in an area that size which could encompass hundreds of people (especially a self-absorbed ass who would use something like this). Even assuming you were completely aware of everything going on in your vicinity, I doubt you could sense important incoming calls. I'm sure the gentleman dining at the table next to you won't mind not receiving the call that the hospital finally has a transplant for him. I'm sure the mom sitting three rows behind you at the theater won't mind missing the call from the babysitter that little Timmy swallowed poison.

B: People will die without mobile phones? This didn't seem to be a concern 20 years ago; landlines still exist, so find one. By law in the US business owners can't block mobile phones in their store unless the building was constructed out of resistant material before hand.
It wouldn't be a problem if people used common courtesy on both ends. Eventually this will be solved with the advent of having mobile phones implanted internally.

C: I would only advise using a jammer in places where cellular telephone usage is highly annoying and socially unacceptable.. i.e. a resturant, movie theatre, classroom, etc. Maybe when some retard on the road isn't paying attention because of his conversation too.
Otherwise, I think it would be best to leave people alone. However, in these situations, it is rather difficult to get caught or for the FCC to do anything about it. If you're running it 24/7 out of your apartment and telling everyone about it, then you do deserve to get caught and it would be much easier to find the source of the interference to implicate you criminally.
Everyone loves to huff and puff indignatly on the Internet. The FCC can't do anything more than try to question you (and you can refuse to talk to them) and try to take signal readings outside your residence.

D: The fact is, cell phone jammer really SAVED alot more live then cellphone ever did... How do you think they prevent remote detonation of bombs? Jammer... You guys clearly aren't cops.
You'll be hard pressed to find any US vehicle in iraq not equipped with one, it's the solution to IED, what do you think soldier do to place a cell call? They just MOVE AWAY from the vehicle ( or turn them off, but that rarely happens ). That's all... The exact same thing you do when you get a low signal, you move to find a better one. You see an emergency ( and of course you don't offer to help! hell you're the all important cell guy who's gonna save the day! ), you move a couple of feet and you get your signal back.
Should we blow up moutains because they block signals?

E: great place to use them is where cell phones are not allowed, like at MANY schools, kids use cell phones to cheat on tests. Too bad those select few of cheaters and other inconsiderate people have to ruin cell phones for the rest of us. I have no beef against cell phones, only how they have become (to some people) a necessity for social life. Last time i checked, you did't need to talk to a friend who is cutting school, while your taking a test.

So, how do you think of this problem?
