Is pointing a gun at someone tantamount to attempted murder in Kenya? If not, what would it most likely be?
Assuming these are common law crimes (Kenya is a common law country - sort of) or statutory crimes that have codified common law crimes without substantially changing them.
It is not attempted murder - this requires an intent to kill. Pulling the trigger would have that intent, pointing it doesn't.
It is assault if it puts the victim in fear of immediate harm (pretty sure it would).
There are probably some statutory firearms offences too.
(In the U.S.) This is at least assault with a deadly weapon, which is typically a felony.
