There's a reason writers should read their work before submitting it. Sometimes our thoughts don't follow the linear pattern to express the correct meaning.

Consider this sentence from an AP article: Harrison eventually lost control of his car and was discovered, shot and injured, by other agents.

As I first read the sentence, I was shocked that Harrison was discovered, shot and injured by the other agents. I was not shocked by the extra comma since erroneous commas are common.

I read the phrase "shot and injured" as verbs when they are really adjectives describing Harrison. The sentence should have read: Harrison, shot and injured, eventually lost control of his car and was discovered by other agents.

Harrison survived, and charges were filed against the suspects, who were not agents.
