First of all, the police don't start "prosecution", the prosecutor does. If you are really an attorney, you should know that. You're wrong, and biased. It is foolish to give the advice that you have to convince the police at the scene that you are innocent as DeafSmith stated. Again, if you are really an attorney, you should know better. The police merely arrest people for crimes. It is the responsibility of the prosecution to convince a jury that you committed it. It is up to your attorney, to convince the jury that you didn't. The jury decideds guilt. NOT the police. The scene of the crime is not a court room. Maybe in your brand of LE the cops are judge, jury and executioner. More people have been sent to prison or wrongly convicted because of the idiotic advice of convincing the police at the scene that you are innocent. It's because of idiotic advice like that that most arrests turn into convictions. Most people are not attorneys and not in a position to adequately represent themselves. Furthermore, again, Cops are not a jury, judge, or attorneys, they have neither the education nor the credentials to decide on legal matters. The best advice is to let counsel who has spent years in law school, passed the bar exam, and has decades of experience under their belt to represent you in such a case. But go ahead, keep telling Joe Bob Farmer to represent himself in front of your fantasy court held by the police at the scene. I'm really starting to doubt that you are really an attorney....or is it that you are also a Cop and enjoy baiting people?
