More than likely you ARE GOING TO JAIL. It doesn’t matter what you say or don’t say. LEO are not the bad guys. Their job is to collect evidence. If you talk at all at the scene it won’t make any difference. It is proven that after a DCI you could/will have missing memories, timeline memories and even false memories. This isn’t your fault it’s just how the internal parts of your brain work. You CANT avoid this.
So, don’t say anything other than what is on your membership card. “I want to cooperate 100% but must have my lawyer present”
