CCTV, Crime and Punishiment

Short:
Continued growth of CCTV coverage.
IP CCTV becomes the favored medium.
More city's use smart camera systems for road pricing, the technology gets better and cheaper.
More countries use smart camera systems for road policing, speeding, dangerous overtaking, bus lanes etc...

Long:
Ubiquitous camera coverage will change policing, probably resulting in fewer cops.
The same ubiquitous coverage could change the legal profession as well, as many crimes will be either directly filmed or have strong circumstantial evidence resulting from filming, resulting in shorter and simpler trials.
