Police

Police cams have suddenly become a big business. But the real money is in selling departments a way to store each day's video. Firms are offering easy uploads to the cloud but costs are bound to grow.

One officer says relations with the public are "about as bad as I've seen," as a take-charge method of policing collides with a more skeptical citizenry that can record and disseminate video anywhere.

An officer's body camera captured his decision not to shoot a possibly armed suspect. He was praised for brave self-restraint, but some law enforcement officers say his reluctance was irresponsible.

Such tragic events offer crucial lessons about policing for other cities. Mainly, they've taught officials the importance of good community relationships and keeping the public informed.
