However, this author points out that a couple arguing in the front yard will behave differently than a couple arguing in the back yard, because the neighbors will not see. It's pretty cool.
That's so true! Although, we have neighbors that fight in the front yard at decibel ranges I doubt I will ever master, and it's to the point we don't even need to look out the window anymore. "It's the neighbors again! Break up already, why don't they?!" If they ever did fight out of sight, one of them might not survive. However, if one of them did end up dead, there's more than ample proof (from us annoyed neighbors) of domestic disturbances, which could easily point the police towards the other, whether or not they were in fact guilty.
As we proved earlier with our series on all the people who inadvertently Clark revealed his secret to, there may be even more people who saw Clark change from Superman to CK (or vice versa) because he wasn't careful enough to check the locations of his changes for possible witnesses.
