Okay. It's just that you didn't state that you feel the law should be changed to permit jamming. So I was curious if you were of the mindset that jamming is a good idea regardless of the current law. That is why I phrased the material that I wrote as a question rather than a statement.
My perspective is that whether you love them or hate them cell phones are a part of modern day life. It is true that in decades gone by we lived without them and we survived well without them. However, like most technology they grew on the populous and became a convenience and, like many technologies the become conveniences over time, society has grown dependent upon them, almost to the point of necessity. Indeed, i can see some good applications for this technology and some that are not so good.
My personal way of dealing with cell phones is, I don't let them bother me.
In as far as BART goes, it seems that the cell phone jamming had nothing to do with preventing people from having annoying conversations. It seems to have everything to do with keeping protesters from communicating. The police have enough trouble dealing with the criminals that ride the BART system.
