So you did , Let me give it a shot.
The topic is whether granny should have been arrested and whether she would have been arrested had the deputy not been moonlighting with the power company.
The second half of your question" whether she would have been arrested had the deputy not been moonlighting with the power company."
I'm guessing that if the Power Co. had called the Police instead of the moonlighting Deputy . No .
But thats why they hired the Deputy in the first place isn't it ?
The first part on whether she should have .It's possible If she caused a danger to herself or others or she broke the law she should have been. If on the other hand she was just being annoying and her crime was holding up the ( expensive) work crew . No
That is possible but doesn't seem likely given that the workers there were surveyors.
