Honestly the best thing to do is just seek representation first, and not say anything to them. 9 times out of 10 they’re going to have a recorded statement. Anything that you say to them, they will probably use against you in the future just to make sure that they mitigate their cost. They are a business, they try and save as much money and cut corners as best as they can.
Anything that you say even though it doesn’t sound like it’s going to be something that will hurt you, they will find a way to turn it against you a lot of times. That’s why like I said it’s important to find representation, and seek an attorney’s help to make sure that you are protecting your own interests.
