Body cameras see in an enclosed area. They don’t see 360 in every direction.
They’re not the solution.
I disagree. A body camera should see exactly what the LEO sees nearly all the time -- not always, but nearly always. Despite what Obama/Holder say, body cameras are not to protect the public, but to protect the LEO. Body cameras should be checked to make sure they work at the start of each shift, and if it suddenly stops working during an encounter, then LEO ought to have a lot of explaining to do.
In my county, all LEO have had cameras on their patrol cars for several years. As a result, the number of DWI prosecutions are down, but the number of convictions are up. Why, because the cops can no longer get away with embellishing truth in order to justify the stop and arrest, and the perps plead guildty when they see themselves on video swerving and staggering all over the road, and as a result the arresting officer's credability is no longer an issue.
