If I saw someone lift up a machine and drop it I'd probably give them a roundhouse to the jaw with my fresh white new balance thus reducing it to bird seed.
While the person was stunned from the first roundhouse, I'd follow up with an axe kick bringing their head through the glass with the force of Thor's hammer.
I don't know how my jean shorts would fair after me exercising this method of justice but you can bet your ass they would be tattered.
