Here are a couple of things wrong with your statement;
1. The garbage truck is not parked in front of your home 24/7
2. Only pictures of license plates are save. No pictures of people are saved. No vehicles parked off the road are photographed.
3. Access to the database is restricted and there will be retention policies in place.
A webcam and license plate scanning are very different and equating the two is invalid.
I cannot believe you actually accept all of this as truth, as if we haven't found rampant abuse of monitoring systems after promises like this shit are made up front to justify the "innocent" program. Hell, I couldn't even make it past #2 in your list without thinking of the stories that came out regarding images gathered by TSA body scanners.
The level of blind faith here fucking floors me.
Considering that the garbage truck will be on your street for a few minutes every week or two it is not monitoring day and night.
I'm not worried about the garbage truck and the "few minutes". I'm worried about years of data being collected and used and abused in ways you've not even thought of by law enforcement.
Do you think streetlight camera databases are never tapped into to track movements of "suspects" (gotta love parallel construction), even though the entire system was justified in order to curb people who cause accidents by running red lights?
Do you think your travel information isn't kept for years to benefit pattern analysis even if you've never even been accused of a crime?
Do you enjoy the fact that you could end up on the No-Fly list with zero explanation as to how you got on the list, or how you could be removed due to your obvious innocence?
How will you feel when they come back in a few years complaining about the limited capability of vehicle mounted cameras and instead propose a fleet of drones to capture images in driveways and parking lots? (of course, they'll pinky-swear they won't point them in your windows or otherwise invade your privacy, and none of that footage will ever be leaked.)
On top of all this, statistics will likely show this monitoring will do fuck-all to stop or curb auto theft. I sure as hell don't expect my auto insurance company to hand me a huge refund if I move to a "monitored" community next week, and chop shops don't usually worry about keeping license plates intact.
