Signs that I Read too Much Science Fiction

I'm reading through a police report and in the section describing the defendant I see this section:

Ethnicity:
H . . . . . NH . . . . . U

As I sit there looking at it, the first thing that pops into my head is "Human . . . Non-Human . . . Unknown."

Now, that's a police department which is prepared for everything. Heck, when the Martians come the department won't even have to change its paperwork.
