An officer of the law, in my opinion, would be anybody who has the power to make an arrest (other than a "citizen's arrest", a very special case). This would mean any police officer. They would have to have a badge to identify them. It definitely does not mean "lawyer". BTW, just to answer schafferleon, I don't know where he comes from, but I would not attempt to bribe any of the U.S. policemen that I have come in contact with. It does happen, of course, but not nearly so often as he would have you believe. As for me, unless I'm speeding, I generally feel safer when the police are around. Also, I haven't hear police referred to as "pigs" by anybody since my college days - longer in the past than I'd like to remember.

fdmaxey is right. Any official who has been entrusted with enforcing the law is an "'officer of the law". There are many types of law enforcement personnel in the US, often with different job titles based on their jurisdiction: cities have police officers, counties have sheriffs, at the State level we have troopers, and there are also highway patrol officers to catch speeders and reckless drivers. Any of these officials could be described as an officer of the law.

WOOP WOOP. Police Officer. We use the terms, Pigs, Fuzz, 5-0, Donut Munchers as slang terms in USA. They are generally very corrupt people, the best thing to do would be to keep quiet at all times around them.
