Shooting a bullet up into the air

Given that there is no wind, if you shoot a bullet straight up, when it comes back down will it be going fast enough to kill someone? I know it won't be going as fast as it was leaving the barrel of the gun because of air resistance on its trip back down, but I'm just wondering if it would still be dangerous.

From:
http://en.wikipedia.org/wiki/Terminal_velocity#Examples:
Higher speeds can be attained if the skydiver pulls in his or her limbs (see also freeflying). In this case, the terminal velocity increases to about 320 km/h (200 mph or 90 m/s),[2] which is also the terminal velocity of the peregrine falcon diving down on its prey.[3] And the same terminal velocity is reached for a typical 150 grain bullet travelling in the downward vertical direction — when it is returning to earth having been fired upwards, or perhaps just dropped from a tower — according to a 1920 U.S. Army Ordnance study.[4]
