The issue of "shotgun microphones" came up last night on FTL, and I'm sure I could rig up something good for any video camera that has a threaded base for mounting to a tripod.
If the video camera were based on top of a van, wired to send data to be recorded at a remote location, in the hands of someone who could switcheroo the recording media with something blank or hand it off to a runner, or handcuffed to the videographer, that would make things a little more difficult for them.
Maybe we could mount the video camera inside a plexiglass box, and cover the outside with pepper spray?
Or set up the box with an "alarm" connected to a smoke grenade. Sure, go ahead, take it for evidence.

Or secure the camera to a block of concrete or a box filled with lead (nope, sorry - don't have any of those laying around

) by a cable. Cut the cable, and set off ... something. Smoke? A REALLY loud alarm on an SCR circuit? A recording about the First Amendment? A Tesla coil?
Maybe just mount it to an open-bottom box filled with squirrels or wolverines.
