Heh to the last sentence above - so then, presumably also doubles up as a audio / video-jammer (which would stop those pesky protesters filming cops and private security thumping ppl at #occupations, etc). Also, gotta love the order in which these two sentences appeared; an unintentional relative importance-signifier (though, more likely just coincidence (laughs)):
"...the primary use would be as a non-lethal weapon for the military to defend sensitive locations from vehicles refusing to stop."
"There has also been police interest."
More unintentional laughs: "...if you took a 1960s Land Rover, there's a good chance you're not going to stop it."
To paraphrase Bill Gibson: when the opposition go Hi-Tech, we go Lo-Tech.
"The firm added that it did not believe the RF Safe-Stop posed any risk to people using a pacemaker."
They do not believe... well, that's okay, then.
