About 2 years ago I worked for a world known security company assigned for loss prevention at a retail store. I was escorting a shoplifter to the office along with the department manager of the retail store when the shoplifter took off towards the exit. When I gave chase I accidently ran into the department manager knocking him down. Now I get a call from the Security company's lawyer saying that he is suing the security company. I have to give a deposition on what happened. She told me she was there to represent the security company not me but I could bring a lawyer if I wanted to. Can I be sued and should I have representation of my own at the deposition?
