JM seems to have had a lot of experience with the courts and DMV, traffic, that sort of violation. He likely picked up his attorneys, if he got any, from those mulling around the courts. He and his family probably thought due to the seriousness of the situation that he would get a public defender. I don't think they understood that he was not being arrested or accused at that point. JM did get time with an attorney who likely clarified the situation to him and told him he did not have to talk to LE and that he should not. This must have been very confusing to him. I'd have been confused too if police showed up at my place at an off time with a warrent to search and seize my car and search my home, and then wanted to talk to me. I don't think LE gives out much info to anyone when this happens, so my reaction too, would have been to get an attorney. So as an innocent person, I'd not be feeling kindly or cooperative at all towards the police at this point in time, and I don't think anyone would even given the seriousness of the missing person. Yes, I'd selfishly be thinking about myself and be scared out of my mind, paranoid and not at all friendly with the police.
I still don't get how LE got a search warrent for the car, was able to seize it, got search warrent for the apts, and yet can't touch the owner of said car, resident of said apartment.
