I don't think that email he posted from legal@google.com is legit.

Look at the first sentence of the first paragraph and the first sentence in the second paragraph. Two grammar errors which are a dead giveaway it's fraudulent.

> Thank you for your assistance and understanding during your recent support call, regarding a ficticious request aimed at accessing your Google account.

Comma doesn't belong there and "fictitious" is misspelled.

> To follow all guidelines of the internal review properly. Please keep a secure note with the temporary password which your support representative has provided to you.

Out of place period. Should be a comma.

Legit, canned emails like this (especially from legal@google.com) would be proofread much better than this. It's fake.
