What happens if a gun was used in the robbery?

A firearm allegation transforms the case. The robbery becomes first-degree under § 11-39-1 with exposure up to life. On top of that, the state will add charges from Title 11 Chapter 47 - most commonly possession of a firearm during a crime of violence - which carries mandatory consecutive prison time that cannot be suspended, deferred, or run concurrently. A second or subsequent firearm offense carries even longer mandatory minimums. Attacking these cases requires fighting the firearm allegation on its own: Was the weapon recovered? Was it operable? Do witnesses actually describe a gun, or just a bulge under clothing? If the firearm charge falls, the mandatory stacking falls with it, and overall exposure drops enormously.
