The fatal shooting in Ferguson, Missouri demonstrates the need for more transparent policing. The facts about the police shooting that sparked the riots are not clear–there is no objective record of what went on. There will surely be testimony from both members of the police force and the public about the incident, but testimony about such incidents on both sides can be biased and indeed even false.
Fortunately, technology empowers us to have better records. Police can wear cameras that record video with sound both during the day and at night. The footage could help determine what actually occurred in incidents like the one in Ferguson. By providing a more objective record, they would also deter misconduct. And they would encourage firmer policing when needed because police would have more confidence that they would not be falsely accused of brutality or murder. Finally, they would make protests less likely as society would be more like to converge on a true understanding of what happened and justice would be swifter.
