All this senseless killing is so disturbing.  They didn't even seem to have a clear reason why this man was shot.  It seems like every day or so there is some lunatic out there with a gun killing people for no apparent reason except for their own instability or anger at the world.  This is such a sad scenario that people see killing others as an outlet for their own negative emotions.  It seems like there is not much of a good solution for this scenario, as controlling guns just takes away protection from people who need it.  The bad guys still find a way to arm themselves.
