motley, you know how DA's interpret the law.  If one piece of glass from a broken vase struck an arm and any detectable mark was left or even if not just based on assertion, the charge would be made.  I laugh every time I read application of the kidnapping charges, with up to life sentences, for dude A holding a door closed for 3 minutes thereby preventing exit of dude B.  The kidnapping statues were not intended for such situations, but in the desperate effort to force that plea bargain, the statues are used.  There is no meaningful restraint on charges applied by the DA.  Even the sound of the vase breaking could construed as causing physical injury to the "victims" ears.
