Upset Austin woman throws dog poop at man

Here's a story from Austin, Texas.  A 46 year-old woman has several charges against her when she reportedly threw feces and a rock at a man and spat on him when he wouldn't clean up after his dog in their apartment complex's dog park.  She also allegedly confronted a man whose dog wasn't on a leash, grabbed the unused leash from the owner's hand and pulled it toward herself.  The dog owner claims the leash cut his hand.

This is clearly not the way to convince irresponsible dog owners to clean up after their dogs, but they charged her with aggravated assault with a deadly weapon?  That seems a bit extreme.
