Seattle Police Department One Of The 1st To Fly Drones (pdf link to SPD Operations Manual/Policies)

Not a lot of Information seems to be out there about this. Just a lot of links to local news stories around the country.
Just my assumption here, but I think the SPD Operations Manual would be what other public agencies would use as well.

The Seattle PD will be flying the Draganflyer X6-ES [link to www.draganfly.com] There is a small screen on the remote, so the operator can see live. Of course a down-link to record as well.

Seattle Police Dept Unmanned Aerial System Operations Manual
[link to spdblotter.seattle.gov]
pdf format and 14 pages long. Tons of info, and not all makes sense.

This one has me at a loss. Per FAA rules agencies (not just SPD) cannot fly drones during darkness. Then in the Seattle Police Dept Unmanned Aerial System Operations Manual, one can read a FLIR capable camera is used (pg6). What the hell?

Could not find a FAA link. But many news agencies report the FCC rules as follows:
Must be flown with a trained operator and spotter.
Keep under 400 feet.
Not be flown in darkness.
Not be flown over large crowds or people. (What the hell, again?)
