Body cameras sees complaints against police ‘virtually vanish’, study finds

Interesting article. I hate when someone comments only to quote a paragraph of the article, but I'll make an exception because reading only the title may be polemic:

> Researchers say this may be down to wearable cameras modifying behaviour through an ‘observer effect’: the awareness that encounters are recorded improves both suspect demeanour and police procedural compliance. Essentially, the “digital witness” of the camera encourages cooler heads to prevail.

Can't wait for the amazing mental gymnastics that some police union will pull to not have them made mandatory.
