Glaring apostrophe error in a book about law for the layman

Ed. has just renewed his membership in the Grammar Police. He has this advice for those who aspire to be published writers.

Apostrophes give many writers a lot of trouble. Sometimes, you might be tempted to put an apostrophe where it does not belong, such as when you are simply making a word plural. 

Other times, you need to make a word possessive, but you might forget to use the apostrophe. 

Then, of course, there is that whole its / it’s thing that confuses most everyone. Remember, the rule is to use an apostrophe when you need to show possession or ownership. 

The exception is with possessive pronouns such as my, your, his, hers, ours, their, and its. "Its" shows ownership while "it’s" is a contraction for "it is". So, just like "hers" and "his" are possessive pronouns that don’t use an apostrophe to show possession, "its" follows the same format. 

For more information on the apostrophe, be sure to check out the Apostrophe section in the Punctuation area of Grammar Essentials of the Excelsior Online Writing Lab. If you just need to brush up your skills, visit the Apostrophe Refresher. 

If  you don't follow these rules, you might end up with a sentence like this: 

Its abundantly clear to me that the rule’s of English grammar can be confusing and following it’s many exceptions even more so! 😒

WRONG! The sentence should read (and be punctuated) like this.

It’s abundantly clear to me that the rules of English grammar can be confusing and following its many exceptions even more so! 😀

Quick quiz: See how many apostrophe errors you can find in the title of the book pictured at left.

Answer: "Juror's", "Sheriff's", "Bailiff's", and "Justice's" are all WRONG, using the possessive form where the plural is wanted. This is not a joke, but a real book, advertised on the Thriftbooks website. We'll have to give the author a pass, as he's obviously a product of American education. And yes, "we'll" and "he's" are correct. They are contractions of "we will" and "he is".
