In the news this week is the arrest of Amanda Bynes for DUI in Los Angeles. However, her father is not just standing by his daughter in the aftermath of her DUI arrest on Friday. He says there is no way she was drunk that night. "She was not drunk," Rick Bynes told People. "I'm told she blew a zero on the Breathalyzer. She didn't have a single drink. My daughter doesn't drink." The elder Bynes claims the police officer that detained his daughter was at fault for pulling out in front of the actress as she was turning at an intersection. While she was arrested for DUI after side-swiping the cop, Rick adamantly says his daughter was not impaired, just extremely "upset and very emotional." So, how is this possible? One possibility is that she was under the influence of drugs, either prescription or illegal drugs. California Law allows a police officer to arrest a person for DUI if the individual was impaired due to alcohol or drugs or both. Time will tell whether the evidence supports a charge of DWI or that the officer was simply mistaken.
