From the article: Police and others say it could stop terrorists from coordinating during an attack, prevent suspects from erasing evidence on wireless devices, simplify arrests and keep inmates from using contraband phones. Now how in the heck is an RF jammer going to prevent the erasing of evidence? I guess if the evidence is stored remotely, you can't send the kill signal or something, but that falls so far into movie-plot terrorism that it isn't even funny. If the police asking for these kinds of new sweeping powers can't even get such a simple technical point right, then why should we trust that crime prevention is the true objective or that they are competent enough to have these powers? Now don't get me wrong-- there's a lot of good cops out there. I think that these kinds of problems are systematic and not individual.
