The guard's gun was only aimed at Melania, just in case it did something bad to Brando, they just waited.
Misty secretly rolled her eyes and saw that the guards were shooting the other mannequins, no one was in the area because they had already run away, all that was left was Brando and his mother and father, Misty frowned. as he sees it, and through her mind she stops the mannequins from moving.
The mannequin's bodies were cracked, others were still intact but their skins were damaged. When the guards saw that the mannequins had stopped, they stopped shootinf but their guns were still pointed. And when they don't really move anymore the guards just stood still and examined it.
