Were those gun shots that I heard

I would first like to premise that all the things that I say are just my thoughts and I in no way investigated to find out whether what I believe is true or whether they are just an imaginary thoughts that run through my mind.
Last night after class I drove up into my driveway an the gate was wide open, which was odd, and noticed that my roommate's, Tom, car was in the driveway talking on the cell phone, man he can talk for hours, I went into the house and later took the dog out of his area so that he could run and play, which he did with great appreciation. I then walked him through a few training techniques; stay, sit, down, and come. Kobe does all these very well but he is a puppy and loses focus rather quickly but as quick as before, I need to do some more tricks and have him turn into the best fighting dog ever, Ala Michael Vick, just kiddin; my dog would be the worst fighter ever since he all he wants to do is play. Well getting back to Tom, he stood in the car and just talked until Kobe finally saw him and started jumping onto the window and putting saliva all over the glass. I eventually prepped the dog food and put Kobe into his place again. Oh, by the way, I decided that I need to workout since my injured Achilles I have gained 30 lbs. as saying go,'More of me to love', yeah right. Oh, I also heard gun shots, and then the helicopter came, but no ambulance, those drive byers are such bad shots!!
