Dunno if we're going to go this way, but I found some archive.org public domain videos of police officers to splice in the final edit like we did for the original They Can't Turn the Lights Off. (There is a high def download available at the site, but my computer is being awful and I can't download it.)

Here's the link: http://www.archive.org/details/your_police

Some parts that may be helpful:

… police officer taking photo :39 - :42 (thought this one was especially good for the subject matter)

… officer shooting a gun :49 - :52

…. officers searching w/ flashlights & arresting a guy 3:43 - 4:05
