I just was charged with Drunk Driving in Princeton, NJ. I blew a .09 on the BAC. I only had 6 drinks.?

I wasn't hurting anyone and didn't crash. Why is there a law against this if no one is harmed. I can understand if I had hit someone or crashed into a car or something. But all I had was a couple of beers and ran into a checkpoint right near princeton new jersey. Anyway, does anyone know a good drunk driving lawyer that can protect my rights and get me off this dwi? I would spend any amount on legal fees to make this go away and not have it hit my driving record. It's not like I was wasted, just had a few drinks and got pulled over by the police and given a breathylizer. They didn't even give me a roadside sobriety test. Also, should I hire an attorney in Princeton, or another town that is closer to the courthouse?
