Well, of course not.
So if you get an email with the return address of FBI OFFICE, and the ALL CAPS subject line reading “WE THE FBI HAVE WARRANT TO ARREST YOU GET BACK TO US FOR YOUR OWN GOOD”, please hit delete. Don’t forward it to a relative or friend asking if they think it is legit; don’t think twice about it, don’t open it … just don’t bother.
And whatever you do, don’t click the attached .txt message “final warning”, or else!
Thank you. That is all. =P
