Given the disgusting events outlined in today's JFK thread, I want to point out just one of the tools available that allow you upload video content in real time to a safe Internet location, so even if you're coerced or forced to delete it from your phone, or your phone is confiscated, the video will remain in a safe place.
I would suggest connecting to a nearby Wifi signal for best performance, but the product might still work over a strong 3G or 4G signal.
