In Florida, the taking of someone else's belonging by force is known as robbery (as opposed to larceny, fraud, or theft). If the robbery is committed with the assistance of a weapon (firearm or other type of weapon considered to be deadly), it is armed robbery and is deemed a 1st degree felony. Other factors which the prosecutor will consider in determination of your particular charge is whether the victim of the robbery was injured. In any case, whether a weapon was used in the commission of a robbery, the crime is a felony, either of the 1st or 2nd degree.
The "10-20-Life" law may come into play in robbery cases. In crimes where a firearm is drawn by the offender, a mandatory sentence of 10 years in prison is the law. It's 20 years in prison if the gun is fired in the commission of a felony. If someone is injured or killed by the firearm it's 25 years to life in prison. These are tough sentences. If you're charged with a robbery, you need an experienced criminal trial lawyer.
