That's true. With the force of gravity, everything falls at the same speed, 
which is about 7 meter per second or something like that (hey, I can't 
remember everything!:)

When the bullet looses momentum, it will begin to fall, and only accelerate 
to the speed gravity allows it, which is the same for everything, be it a 
bullet or a bus (give and take for air resistance).

Now, at this speed, I'm sure someone could get -hurt- but a bullet, but 
seriously injured or killed is unlikely.
