Can a repossession company come into your garage or refuse to leave your premises?

Question Details:

In an attempt to repossess our car and man ran into the garage as we were pulling in. I did not know who he was or what he wanted . He shoved me from the car trying to get my purse and keys. My husband came to help and was placed in a choke hold and pushed down on his knees. I continued to ask him over and over who are you , what do you want. He took his shoulder and slammed me up against the car and said he was here for the car. A car pulled into the edge of the garage behind me and a woman came running into the garage yelling. They would leave or identify themselves. What can I do? Important Notice
