#7 must be for leftists.
Should add some more...
#8 if you can film from long distance using a good zoom lens, awesome, load that video onto YouTube faster than cops can say "where are the doughnuts"! Avoids a lot of hassles.
#9 flash mob filming - get enough people recording, good luck trying to bust 'em all before they can run off and post vid's!
And really, what cop worth a damn is going to freak out over a citizen taping an event if they are not interfering? Come on, if these officers are that paranoid they either have something to hide or perhaps they should find a less demanding career somewhere else!
