Las Vegas Police have reported just sixteen arrests on the Strip and at Fremont Street on New Year's Eve Monday night. The most serious charge involved a twenty-year old man who allegedly brandished a firearm in Circus Circus. He's facing several charges including the Nevada crime of assault with a deadly weapon.
The Nevada crime of assault with a deadly weapon occurs when someone uses a deadly weapon to put another person in reasonable apprehension of immediate physical harm. Note that it's unnecessary that the suspect actually use or wave the weapon...a person faces liability merely for having a weapon on his/her person during the assault. A common example is pulling a knife out on someone or throwing a punch while wearing brass knuckles.
