In one word: Cameras. If you live in a city, you should probably assume there's at least one camera watching you at all times, never mind the phones that are whipped out the second anything interesting happens. Reporters who cover the courts now report that basically every case features video compilations that track every moment of the suspect's day, as well as that of the victim. Through security cameras, store cameras, traffic cameras, even doorbell cameras—it's impossible not to be seen.On one hand, solving murders is a good thing. On the other hand is ... everything that goes along with living in an age where you're under surveillance the moment you step out your door, and where the police have many more video resources than the average defendant ever will.GUEST: Alyshah Hasham, former crime and courts reporter, current city hall reporter, Toronto Star
