	"[Side question: does anyone know how such a recording system
might work?  Loop tape of a certain length, I'd assume...]"

I had occasion to stop by our local (Brighton, N.Y.) police HQ last
year.  In the office in plain view on a table was a large 1/4"
reel-to-reel tape deck with 10" reels turning at what looked like 1
7/8 ips (the standard "slow" speed for reel-to-reel).  It was
recording both phone conversations and police radio.  It also had a
digital clock on it that looked like it was counting in SMPTE time
codes, so I would guess it records time data as well as voice.  I
didn't ask how long they kept the tapes.
