Even an ice skate from that same aisle would do the trick I suppose, maybe even a broken, jagged cricket bat for that matter.  
Today's event perhaps might be a cultural mis-understanding. As such, maybe criminal charges should be sensitive to the cultural fact that different people expect their females to be held to a higher standard than traditional colonional norms.
Based on the culture of the accused, are such severe charges even warranated ?
Canada is multi-cultural, we should be more open to ALL facets of that policy.  
A white man's crime, might be another's defence of honour....
