Florida man caught in legal limbo for filming police.

There are smartphone apps now that allow video to be recorded directly to online storage. Eventually every video recorder will have this capability. The idea of confiscation for evidence will become a lot more complicated (and unenforceable). And in line with my pro-surveillance stance, the way it should be.

If you are doing your job properly and within the law, there should be no problem with anyone filming in a public place.

They should have seized the phone as evidence and left it at that. Unless the officers had something to hide. There is a reason we are expected to not only act, but BE professionals. If you're professional in your actions, and you observe someone recording an incident you're involved in, finish your business and then approach the individual recording. Inform them that you would like to seize their phone for evidence, since the video they took can be used in court. That's usually enough to make most people delete what they recorded. If not, then seize it. Either way, you should always be aware of your surroundings and act accordingly. When all else fails, always assume you're being recorded.
