The eyes have it

We don't have enough surveillance. They're missing huge possibilities, cameras on the roads and buildings are all very well but where are the cameras in cars and in houses. An internal camera in every car coupled with a sensor and you can spot a drunk driver before he even sets off, something sniffing the air will pick up drugs. We could even take it further and wire up one of those devices that diabetics use to shove a little needle in your thumb when you grab the steering wheel to take a blood sample. Simplicity itself then to have the car self-lock, contact the police via the ever present mobile phone which will also give them the exact location via GPS.
See we're all instantly much safer on the roads.

All new houses and a 3 year limit for converting existing housing to have Webcams installed in every room. Think of all the domestic violence that would pick up and if your not doing anything wrong what have you got to fear? We could even use them to check when those working for the government we're legitimately sick or just fancy a day off, any doubt and the sensors in the room would breathalyse the individual and automatically dock their pay. I'm sure that for a suitable fee the government would allow certain trusted private companies to access the technology.

We could even track individuals by chipping them at birth much like we do our pets. We would need external visual proof of having been chipped though. Due to the density of population in cities scanning for individuals would be just a bit too difficult at the moment. Maybe we could tattoo people with a number or bar code somewhere visible, like the outside of the forearm.

I'm sorry I have to go now, the phone is ringing and it's probably the government Proctologist arranging the appointment to have the camera installed to track my every movement.
