Who is the real bad guy

So a lot of you tend to call my clients criminals, and I'm assuming that it follows that they lie. What a lot of you don't realize is that more often than not its the police officer who tends to spin the truth quite a bit. I can not count how many times I have had police officers lie to my face when I know for a fact, based on another police officer or their very own report, that what they said is wrong. I'm currently preparing a DUI case for trial this coming Monday, and the officer who wrote the arrest report has my client in the car when the officer showed up. The officer who wrote the accident report says my client wasn't in the car, and that he was walking around. Why does this matter? The state must prove that my client had actual physical control of the vehicle. The police officer knows this. So to make sure he gets his DUI, he puts down that my client was in the car, behind the wheel, with the keys in the ignition and the car in drive. Um, how is that possible if the car was in an accident, and it took you 10 minutes to get to the scene? Wouldn't the car just continue driving?!?! I never get used to a lying police officer.
