More on my job

So I just got forwarded a super-serious email thread where one of my coworkers is responding to an upset person about a very serious issue (I'd call the upset person's tone acrid). The upset person was using this sig line "Actus non facit reum nisi mens est rea," which I asked about (since my Latin teacher died in the middle of the school year), and was sent this explanatory URL. Yeah.
