3/3     The Ray Gun
        http://60minutes.yahoo.com/segment/145/the_ray_gun
        Takes ~5sec to stop only one rioter.  How efficient for such an
        costly piece of machinery.  And why can't a rioter wear aluminum
        foil underneath the clothes?
        \_ When the Red Sox won the world series a few years ago,
           a woman was killed by being hit in the eye with a rubber
           bullet as police tried to control the "celebration" in
           Boston.  The ray gun won't kill people.
           \_ It also is a big bulky expensive humvee that is designed
              apparently for precision aiming from long distances. Not
              likely to be helpful in most situations.
              \_ Yes, the present prototypes are big, bulky, and
                 expensive.
           \_ And, like tasers, they will gradually be seen as reasonable
              force and police will use them on people for giving them the
              respect they think they are due.
              \_ What if the rioters wrap themselves in cheap o' aluminum
                 foil?
                 \_ I'm not talking about rioters.  I'm talking about shit
                    like "Don't tase me bro" dude.
           \_ If the ray gun is pointed at the eye by chance like the rubber
              bullet gun was, will the person go half-blind and sue?
              \_ Only if you somehow manage to face into it and not blink
                 for an extended period of time.
           \_ Water cannon on firetrucks won't kill people either, and you
              don't need all that money to develop and manufacture it just for
              this purpose.
              \_ They have been known to cause permanent harm to people.
                 Being hit with a water cannon can be fatal, too, if you
                 get hit wrong.
