That was a scary situation for you. They were threatening towards you. Since you have video of everything, I wonder if they need to be charged.
Why would they let their dog run around you like that. Clearly the pit bull is a big dog. Were they wanting their dog to get hurt. 
Tying him up and leaving him outside in the heat is dangerous for the dog. They are not responsible pet owners.

I am glad they are leaving you alone now. It was not much fun for you and the pit bull with all that odd behavior.
You are just trying to do your job. You really don't need people acting like that.

I hope you are okay. Stuff like this can be really upsetting.
