What are you worried about the government setting you up for? Seems to me they already have more powers than they should and if they want to render you to Iraq for interrogation they will. I'm heartened by the pushback against these powers, and also by court victories that are likely to affirm we have the right to videotape police. Abusive police are on the decline and our right and ability to tape them will frustrate and limit those that remain. In general, government corruption in many states is declining.
I think my chances are much higher that I'll be the victim of ordinary criminals than of the government. Not to mention my chance of being hit by a car. I think in ten years the good, defensive drivers will have wide angle cameras on the dash and out the rear window recording the last five minutes in a loop. Soon enough drivers will have them that many accidents are caught on tape along with plates and faces. Bad drivers will have to shape up or be reported and caught. If the loop is longer, like 30 minutes, police will have an app for smartphones. The app could check every fifteen minutes to see if there's been a police request for video footage from people driving on certain sections of streets where a crime just happened. Then the car cameras could help convict criminals for what they're doing along side the roads. So it's possible the public, wanting to defend themselves and help catch criminals, will set up a surveillance system of its own.
