Is comma required?

Not required.

Not required.

The comma before "and" is not required though can be used if one wishes. The others are required.

Re: Is comma required?


Not only is the comma after "time" not required, but it is wrong. Let's simplify:

Mike's actions were necessary and were later considered self-defense.

A compound sentence (one subject, two verbs) should not have a comma separating the verbs.

The correct full sentence:

Mike's actions, though hostile, were necessary at the time and were later considered self-defense by a jury.

Ah! Welcome back, Roberta!

Had second thoughts about posting, Mame. Did I say anything that made sense? I'm guessing I did, or you wouldn't have said what you said.

You were right on, as usual... got your brace on?

Thanks, everybody, for your reply.

Regards.

It's on. Oy.

Roberta you are spot on. I reread the sentence and slapped myself in the forehead. But the other two commas are definitely required.

Yup, Nick. The other two commas are required. Hope you didn't hurt yourself.
