Funny seeing your quote in your sig, Ryan. A fellow Trooper that handles firearms cases had that same quote attached to the bottom of his work email for about a month. Finally, a higher up brass saw it in an email and made him change it.
Emails are subject to disclosure via subpoena and FOIA. It would be incredibly foolish to put that out in an official capacity. Someday he could see that in 72 point font on an easel in a court room. Not that I don't completely agree with GEN Mattis and the trooper.
