My question involves criminal law for the state of: California and my situation is this, I was pulled over for having expired tags and was asked to exit my vehicle. I was asked if I had ever been arrested and what for, I replied yes for speed. I was asked when I last used and I responded with about five years ago. I was then placed in the back of their car while they searched my vehicle and found nothing. The officer was insistant that I was probably high right then I didn't respond. He then had his partner put cuffs on me and told me just to tell them the "truth" and they would just give me a citation. Then I was told if I just tell them what they want to hear he would instruct the tow yard not to put a 30 day hold on my car and that I could pick it up upon my release (as I was thinkin just a citation lol ). Now I live on SSD and I have conservatorship over my severely mentally handicapped Uncle and a son in grade school the next city over. So I said to him if I tell you I'm dirty you won't hold my car for thirty days and if I dont my car is basically gone and he replied thats right. So I admitted I used the night prior to this. My Question is this, I was in a police custodial situation being handcuffed and in the back of their patrol car, I was never givin my Miranda rights and I was being coerced into making involuntary self incriminating statements. Do I have any ground to stand on here and if so how should I proceeed.
