Terrible Ending to a great day...

In case no one knows the history on our dog Torre, I will give you a brief summary.  We adopted her March of last year and she was a rescue dog.  We didn't really know her history because Humane Society basically said have a nice day and off we went.  It started with close to a 1,000 dollars in doctor bills for her with having kennel cough which led to pneumonia, which led to her overnight stay at the vet because she got so sick at Humane Society.  We found out she really doesn't like other dogs, which I have a feeling came from her previous owners.  Torre is the most loving dog ever, ask any of my family.  She loves my nieces and nephews and doesn't bit or do anything that would scare the kids.  She loves being petted, cuddles anything to do with love.  The only problem we have with her is the other dog issue.  We have tried socialization classes and it honestly did nothing.  Whatever her previous owners did to make her this way I have no idea.  Some days it's frustrating but for the most part she is a loveable dog and we wouldn't change anything about her. 
Sunday was an awesome day, Evan and I skied all day in the sun and came home to get ready to go to family dinner.  We had an awesome time at dinner celebrating Winter's birthday and then started to head home.  Keep in mind we take our dogs everywhere.  We arrived back at our house and someone was in our parking slot (this is my biggest pet peeve ever) so we had to park in the common area.  This always makes me nervous, with Torre's past etc. but she is super good about listening to Evan.  So we all started to unload the car, I let the girls out and started to head back to our house since it is a longer walk.  Before we knew it we heard barking and yelling, and Evan was incredibly quick to yell for Torre to come back and she ran back to us with the owner swearing at us (classy right?)  So Evan is telling him we can't hear him because he is continuing to yell at us and we are concerned with getting our dogs inside, considering this has never happened to us before.  As soon as we get inside we go about our normal business and Evan goes back outside to get the rest of the stuff out of the car.  To his surprise he is met by this man and his wife demanding our names, phone number, etc and will be calling the police since our dog apparently attacked him and his little rat dog.  Evan comes back inside and tells me all this and we both are in a giant state of anxiety.  We have never owned dogs by ourselves, let alone having any trouble with the law.  Sharon calmed us down a bit when we went back over to her house, but I couldn't sleep.  So at 11:30pm last night we have a pounding at our door with a cop needing to file our paperwork for this "attack".  He gave some smart remarks to our dogs considering they were barking at him, which he commented we don't need two attacks tonight (um, hi you are the one at my door at 11:30 at night, they have every right to bark at you)  I didn't find him nice, helpful, basically nothing.  He couldn't give us any information except for the guy  has a laceration on his hand, which Torre has NEVER bitten a human ever.  I can guarantee he put his hand in the way, which of course makes our dog look worse for biting a person.  The whole thing is completely upsetting and I'm well aware our dog was off the leash so we are in the wrong, but I'm still allowed to be upset.  So if you feel on commenting on this blog, please don't give me the 10 cent comment about how bad we are as owners having our dog off the leash.  Trust me we have gotten plenty of that.
