Identify Each Speaker That Gives an Argument for His or Her

Short Answer

Identify each speaker that gives an argument for his or her position in the following passage.
First Citizen: There has been a lot of talk in favor of having civilian police-review boards monitor law enforcement activities. That's better than letting internal-affairs units try to do that job.
Second Citizen: Right. The ethics of law enforcers is as important as the ethics of lawmakers. Letting them police themselves is like having the foxes guard the henhouse.
